Review: KDE neon 5.25

It has been a long time since I've reviewed a Linux distribution on this blog; the last one was of Linux Mint 19 "Tara" from 4 years ago [LINK]. In a more recent post about problems that I had with a scanner that required me to install Linux Mint 20 "Ulyana" MATE because the existing operating system was damaged beyond repair [LINK], I explained that I had come to trust the consistency & stability of Linux Mint enough and liked it enough that, in conjunction with the lack of novelty in Linux distributions compared to 10 years prior, I no longer felt motivated to do such reviews. Thus, it may seem strange that I should do a review like this now. In truth, the motivation wasn't hugely compelling, but I thought it might make for a nice post on this blog as I didn't have much else in mind. I thought of checking out a showcase of KDE, namely KDE neon, because it had been a long time since I tried KDE and I was getting a little concerned that the odd artifacts I was starting to see in Linux Mint 20 "Ulyana" MATE when hovering over right-click menus might be the tip of an iceberg of problems. While the latter concern has thankfully not come to pass even after several months of experiencing these more minor issues, I figured it might be nice to see what KDE is like now.

Default desktop, before changes

This review will be a bit different from past reviews. In particular, in past reviews, I took the perspective of a newbie to Linux trying to do ordinary tasks, whereas the purpose of this review is to see whether I can replicate the look & feel of my desktop in Linux Mint 20 "Ulyana" MATE. Thus, I will focus mostly on changing the desktop and on using the default KDE applications; I will not focus on the presence or absence of other applications or on other parts of the live USB environment.

Revisited: Linux Mint 18.3 "Sylvia" KDE

Main screen + KDE Main Menu

Long-time readers of the Linux distribution reviews on this blog know that I am a fan of Linux Mint, but I have had somewhat mixed experiences with KDE. When I've reviewed a new release of Linux Mint, I have occasionally reviewed its KDE edition in addition to its GNOME/MATE/Cinnamon and Xfce editions, generally finding that the KDE edition has too many minor bugs and not enough compelling features compared to the more mainstream editions. Apparently the Linux Mint developers feel similarly, as this is the last release of a KDE edition for Linux Mint; henceforth, they are only releasing MATE, Cinnamon, and Xfce editions for a tighter focus on GTK-based DEs and applications. With that in mind, I figured it was worth reviewing a KDE edition of Linux Mint one final time. I tested it on a live USB system made with the "dd" command. Follow the jump to see what it's like.

Review: KDE neon 5.9.1

It has been a while since I've done a review of a Linux distribution. Lately, I've seen a few reviews of KDE neon (the second word being intentionally written in lowercase), and some of them have praised it as being much better than Kubuntu (the traditionally KDE spin of Ubuntu). That got my attention, so I figured I should check it out.

Main Screen + Kickoff Menu

KDE neon is essentially a showcase of the latest and greatest version of KDE, packaged atop the most recent LTS release of Ubuntu. It specifically does not officially support any other DEs (though of course users can try as they like), and it is meant to provide the stability of the Ubuntu LTS base in conjunction with the newest features from KDE. It has several versions available, depending on how adventurous one feels in using new software; some of the versions claim to be made for "everyday users", which I take to include Linux newbies, so as usual, I will evaluate this distribution from that perspective. In particular, I downloaded the User Edition (not the User LTS Edition, which features the latest LTS version of KDE, though all editions feature the latest Ubuntu LTS base) and wrote it to a USB via UnetBootin. Follow the jump to see what it's like.

Revisited: Linux Mint 18 "Sarah" KDE + Xfce

The KDE and Xfce editions of Linux Mint 18 "Sarah" recently came out. Over a month ago, I had reviewed the MATE edition, and while I was generally happy with how it worked, there were a handful of minor usability issues and other niggles that detracted from the experience enough that I couldn't recommend that a newbie install it by him/herself. Given that, I wanted to see if maybe the KDE or Xfce editions could make up for the deficiencies that I observed in the MATE edition. Follow the jump to see what each is like. Given that the main base of Linux Mint 18 "Sarah" is common to all of these editions, I'm not going to spend too much time rehashing things like application installation for their own sake; instead, these reviews will be shorter, and will focus on the differences relative to the MATE edition.

Review: Manjaro Linux 0.8.13 "Ascella" KDE

Main Screen + KDE Kickoff Menu

It has been several months since I last checked out Manjaro Linux. That review was of its Xfce edition, whereas this is of its KDE edition. As I mentioned in my recent review of SolydK, I wanted to originally compare the two in a single post. However, Manjaro Linux uses KDE 5 (again, I know this is a deliberate abuse of notation) whereas SolydK still uses KDE 4, so I feel like it wouldn't be fair to compare the two in one post. Instead, I have kept the two posts separate, and will make reference to my review of SolydK as needed.

I tested the 64-bit version of Manjaro Linux on a live USB system made with UnetBootin. Interestingly, unlike my previous review of Manjaro Linux, no extra modifications were needed after UnetBootin finished doing its thing. Anyway, follow the jump to see what it's like. (Regarding the title, some sites say that the codename for this release is also "Ascella", but this doesn't seem to be officially used in an entirely consistent manner.)

Review: SolydK 201506

Main Screen + KDE Kickoff Menu

Originally, I wanted this post to be a comparison test. Specifically, I wanted to compare SolydK to the KDE edition of Manjaro Linux. However, it turns out that Manjaro Linux uses KDE 5 (I know this is a deliberate abuse of notation), while SolydK uses KDE 4. That doesn't sound like a fair comparison, so I'm splitting these into separate reviews.

SolydXK is a pair of distributions that are basically like Linux Mint Debian, except with KDE (SolydK) or Xfce (SolydX) rather than MATE or Cinnamon, given that Linux Mint Debian discontinued its Xfce edition a while ago (and never really had a KDE edition). As far as I can tell, unlike Linux Mint Debian, SolydXK remains a semi-rolling release, as its website says that users never need to reinstall (which wouldn't be true if it had pegged itself to Debian Stable).

I tested SolydK as a live USB system made with UnetBootin. Follow the jump to see what it's like.

Review: Linux Mint 15 "Olivia" KDE + Xfce

I realize that I haven't posted anything in the last 2.5 weeks. That's because in that time I got quite busy with a combination of UROP work, video making for the MIT-K12 project, and studying for the General and Physics GREs. Given that I will be taking the General GRE in just over a week, and given that I will be going home for vacation shortly thereafter, I won't be able to post much after this for this month aside from a probable post reflecting on the summer. That said, it is a Sunday as I write this, and I figured I could use a break from the studying. So to do that, I'm reviewing Linux Mint 15 "Olivia" KDE and Xfce.

Main Screen + KDE Kickoff Menu

Why am I doing this if I have already reviewed the MATE and Cinnamon editions? Well, if you remember those reviews, I felt a little let down by both; granted, I could still recommend the MATE edition to newbies, but it wasn't with the same confidence as in the past. I want to see if the latest version of Linux Mint can redeem itself through the KDE or Xfce editions.

I tried each separately through a live USB system made with UnetBootin. Follow the jump to see what each is like.

Review: SolydXK 2013.04.06

I originally wanted to do this one before final exams, but other hiccups in this review pushed that to now. Anyway, here it is.

Main Screen + KDE Kickoff Menu

What is SolydXK? Debian-based Linux Mint never had a KDE edition, so SolydK was born out of the unofficial project featuring KDE in Debian-based Linux Mint. Then, Linux Mint pushed its Xfce edition back to an Ubuntu base, necessitating the emergence of SolydX. Together they form SolydXK, based on Debian Testing but with update packs, just as Debian-based Linux Mint is.

I tried SolydXK on separate partitions of a live USB with UnetBootin, as MultiSystem did not recognize SolydXK (and that's why I was having trouble doing this review before final exams). Follow the jump to see what they are like.

Review: Pardus 2013 KDE

My spring break is coming to an end (I only have 1.5 more days), so I figured it might be nice to do another review while I still can. Today I'm reviewing Pardus 2013.

Main Screen + KDE Kickoff Menu

Pardus is a distribution developed at least in part by the Turkish military. It used to not be based on any other distribution and used its unique PISI package management system, which featured delta upgrades (meaning that only the differences between package versions would be applied for upgrades, greatly reducing their size). Since then, though, the organization largely responsible for the development of Pardus went through some troubles. One result was the forking of Pardus into PISI Linux to further develop the original alpha release of Pardus 2013. The other result was the rebasing of Pardus on Debian, abandoning PISI in that regard. Now Pardus 2013 is a distribution based on Debian 7 "Wheezy" that uses either KDE 4.8 or GNOME 3 (whatever version is packaged in the latest version of Debian, though I'm not sure what that is).

I reviewed Pardus on a live USB made with MultiSystem. Follow the jump to see what it's like.

Review: Mandriva 2011 "Hydrogen"

Before I begin, I'd like to say that the reason why there was no "Featured Comments" post this week was because there were no comments on last week's posts. That's probably because I didn't write a lot last week as I was spending time with friends and family. Anyway, let's get on with the review.

Main Screen

I don't think Mandriva particularly needs an introduction. Suffice it to say that it was among the original premiere easy-to-use Linux distributions, along with MEPIS, even before Ubuntu existed. It came up with the all-in-one Mandrake Control Center (now, of course, the Mandriva Control Center) and made graphical installations easier to do. It has continued with a dedicated following, but in recent months it almost collapsed, even prompting the introduction of Mageia, a fork dedicated to advancing Mandriva while staying true to its core values (more on that shortly). Its financial woes have continued, but while the last few releases made a few changes to the implementation of KDE 4 but overall nothing too drastic, this release aims to bring back some of the old luster by completely rethinking the way KDE 4 is supposed to work. Let's see how true that is in a bit.

I tested Mandriva 2011 "Hydrogen" on a live USB, first made with MultiSystem and then made with UnetBootin. I was surprised that Mandriva booted after having the live USB made with UnetBootin, because for the last few years Mandriva ISO files have failed to work right with UnetBootin. I guess that application has gotten better at properly writing these ISO files to USB sticks. I tested the installation procedure in a VirtualBox VM in a Pinguy OS 11.04 Mini UnetBootin-created live USB host with 1024 MB of RAM allocated to the guest OS; I initially tried to do the VM thing within the Mandriva live USB system, but that failed (more on that later), and anyway, using Pinguy OS ensured better consistency.

I don't think I've ever written about testing a system with both MultiSystem and UnetBootin. So why have I done so this time? Well, this was originally supposed to be a comparison test with Mageia 1 included. However, Mageia was not recognized by MultiSystem, and the UnetBootin-created Mageia live USB failed to boot properly. That was odd, considering that there were reports of older alpha and beta releases of Mageia that booted fine when the live USB was created with UnetBootin. I think I'll hold off trying out Mageia until it is supported by MultiSystem, at which point I'll review it separately but through the lens of a comparison test, sort of like how I approached Scientific Linux 6 and CentOS 6. In any case, I'm too impatient to hold off testing Mandriva for the sake of Mageia. Also note that while I made all the following observations about Mandriva in MultiSystem, I was able to replicate all of them in UnetBootin, as I have seen with other distributions as well.
With all this in mind, follow the jump to see what Mandriva 2011 "Hydrogen" is like.

Review: PCLinuxOS 2011.6 KDE

Main Screen

The last time I tried out PCLinuxOS was at version 2010.07, and I tried the KDE version then too. I didn't particularly it then because I felt it dropped a lot of useful applications from the 2009.2 release (which I tried out before I started this blog), and because it was pretty slow on my computer. Then again, my perspectives and desires have changed a little bit since then, so don't read too much into that. Anyway, version 2011.6 has been released, and I'm reviewing it.

So what is PCLinuxOS? A long time ago in a galaxy that we are all in, PCLinuxOS was a Mandriva derivative with a custom theme, some changed default applications, and a few customization scripts. Since then, it has grown and diverged into basically its own distribution; really, the only thing it has in common with Mandriva is its package file type, and that is a particular form of RPM used in Mandriva. Other than that, it's basically entirely different, so there's no point in continuing to mention Mandriva after this. Anyway, it primarily uses KDE, though there are GNOME, Xfce, LXDE, and Enlightenment editions available as well. Its selling points include ease of use even for total newbies to Linux, stability, and a rolling-release model. Through it all, it has essentially remained a one-man project, and that man is Bill Reynolds, also known as "Texstar". How can stability be reconciled with a rolling-release model? Well, although packages are sent to the repositories when ready, "when ready" is only after a lot of time and testing. PCLinuxOS is known for its rather conservative stance on upgrading to newer pieces of software; for example, KDE 4 wasn't available for users at large until last year with the release of the PCLinuxOS 2010 series. This is a similar tack Debian-based Linux Mint will be taking by thoroughly testing all incoming Debian Testing packages and only releasing them when ready in monthly packages.

I tested the live session on a live USB made with MultiSystem. I tested the installation in VirtualBox within that live USB session with 1024 MB of RAM allocated to the guest OS. Follow the jump to see what it's like.

Review: Porteus 1.0

64-bit: Main Screen

Considering that I reviewed Zenwalk 7.0 not too long ago, I must be going on a Slackware-derived binge or something. Yes, both Zenwalk and Porteus are based on Slackware. Maybe my subconscious is trying to make up for the terrible review (not my assessment of Slackware, but my skill level and writing in that post) of Slackware 13.1. Maybe. I don't know. Anyway, Porteus 1.0 came out yesterday, so I decided to review it.

So what is Porteus? As I just said, it's based on Slackware, but it's more than that. As Slackware has never had an official project for creating Slackware live media, Slax came in to fill in that void. Quite a while ago, Slax ceased regular development, so after a while, Porteus came in to succeed it. Now, typically, these stories of evolution and succession aren't of much consequence (e.g. AriOS coming from mFatOS, Kororaa moving from Gentoo to Fedora, et cetera), but as you will see, it is quite important here that Porteus is the revived and modernized Slax project.

32-bit: Main Screen

Porteus comes in 32- and 64-bit flavors. Curiously, while LXDE is available for both architectures, KDE 3.5 Trinity is found exclusively in the 32-bit version, while KDE 4 is found exclusively in the 64-bit version. As my laptop has 64-bit hardware, I tested both using a live USB made with MultiSystem. I didn't test the installation because apparently the installation isn't one in the traditional sense; it's essentially booting the live medium off of a hard drive, which seems hard to achieve with not-particularly-interesting results. Follow the jump to see what it's like.

Revisited: KDE 4.6

Main Screen

I recently tried reviewing KDE 4.6, and it didn't turn out so well due to the combination of my installing KDE 4.6 in a live session and my using Linux Mint to try it out. (Also, I have said this before in previous articles, but again, my primary distribution is Linux Mint with GNOME, so that bias will show in this article somehow or another. Please do keep that in mind when reading this.) One frequent suggestion was to use Arch to test it next time. Although installing Arch may not be so bad, getting it configured to work right post-installation, while ultimately very rewarding, is time-consuming and pretty difficult, and I don't think I have either the time or skill to do that. Then I had an epiphany (no pun intended): use ArchBang. It comes as a live CD and, after installation, it has a nice Openbox setup with things like sound and network settings configured properly out-of-the-box. It also comes with a whole bunch of GTK+ applications, so it's ideal to see how well KDE plays with another DE/WM side-by-side.

I tried doing all this in VirtualBox on a Linux Mint 10 "Julia" GNOME live USB, because MultiSystem, the multiboot live USB creation tool, seems to have messed up VirtualBox on my installed Linux Mint 9 "Isadora" GNOME system. I allocated 1024 MB of RAM to the guest OS, used a 10 GB virtual hard drive located on my physical hard drive for installing ArchBang, and went on my way. The installation procedure was fairly straightforward; it was a text-based ncurses-esque interface. After installing, I restarted the virtual machine and then ran the following commands in sequence in order to update the system: "su", "pacman -Syu", "exit", log out, log back in, "su", "pacman -Syu" for good measure, "pacman -S kde", and finally "exit". I also edited the ~/.xinitrc file to start KDE instead of Openbox by default. I then logged out and logged back in. Follow the jump to see what KDE 4.6 is really like.

Review: Mandriva 2010.1 Spring

Main Screen

Before I do anything else, I want to apologize to readers of this blog (and of Linux Today) as well as to the Mandriva community for giving Mandriva such short shrift in my comparison of KDE distributions for newbies. As I did this test separately (full disclosure: I also wanted to try desktop effects, so Mandriva gets 1 GB of RAM and 128 MB of video memory, while all of the distributions tested on my old computer got 448 MB of RAM and 12 MB of video memory), comparing Mandriva's performance against the others' isn't quite fair, so I won't compare them. My reasoning in the article for not testing Mandriva was that PCLinuxOS uses some Mandriva repositories and tools and seems to support more hardware than Mandriva, so it would be a better contender in the comparison. (It's like why I would choose Linux Mint over Ubuntu in a comparison of GNOME distributions.) Furthermore, Mandriva has been going through a roller-coaster ride of a financial situation of late, so I'm not entirely sure how much longer it will be around in its current incarnation. While the second point still stands, I stand corrected with regard to the first point. Please follow the jump to see why I am so sorry that I chose not to include Mandriva in the last comparison.

KDE 4.3 - A Second Look

This comes after I (unsuccessfully) tried to install the new KDE 4.4 on my computer. It seems that Ubuntu hasn't come with packages for versions earlier than 9.04 "Jaunty Jackalope"; the only packages are those available for 9.10 "Karmic Koala" and the (currently beta) 10.04 LTS "Lucid Lynx". I use Linux Mint 7 "Gloria" which is the equivalent of Ubuntu 9.04 "Jaunty Jackalope", so I found myself out of luck. It is my intention to upgrade this computer to Linux Mint 9 "Isadora" when that comes out; hopefully I will be able to get the new KDE packages then, as I am eager to try them out. Until then, I thought of taking another look at KDE 4.3 (which I had already installed and reviewed), as I thought some of my comments were a bit unfair. I found that KDE 4.3 redeemed the old problems (to an extent) while presenting new problems. I have been doing this for about a week.
First, I want to review and maybe show how KDE managed to rectify the old problems.
The biggest annoyance was the lack of integration of Mozilla Firefox, OpenOffice.org, and GTK+ applications. I have since learned that there is a theme for GTK+ applications called QtCurve to integrate them into KDE 4.X. I'm not going to do that as I want to have a native look in GNOME as well; it's a shame that KDE can't integrate GTK+ applications even close to as well as GNOME integrates Qt applications. I know a lot of distributions with KDE 4.X have this theme for included GTK+ applications, but as I also use GNOME, I won't be following this.
OpenOffice.org is a nightmare in this regard. As it turns out, the theme management for OpenOffice.org is near-dysfunctional; even in GNOME, I can't even change the theme to one of the included themes (forget installing a new one).
Firefox is a bit better. I installed the KFirefox theme which gives the menu a look combining the Windows Firefox back/forward buttons with the Konqueror look for the other menu buttons and the scrollbars. Sadly, the buttons in the webpages still look like they come from Windows 3.X. Oh well, at least it is a little better than before.
The Facebook Plasmoid still doesn't work. Oh well.
On a brighter note, Plasma has not crashed on me. KDE also seems notably more responsive and snappy (and quick to load) now. Maybe the latest update brought a serious shot in the arm for speed. That's good.
I managed to fix the problem of window labels in the Task Manager showing up across all virtual desktops, defeating the purpose of virtual desktops. There is an option in Task Manager to turn this off, so that in any given virtual desktop, the Task Manager will only show window labels from that virtual desktop. It's a good improvement, but I would like to see it like that by default in the future as in Linux Mint GNOME's default behavior (once the virtual desktop panel application is added to the panel).
I changed the main menu to the "Lancelot" menu, which is a slab menu similar to Linux Mint's MintMenu. I like it as I like all slab menus, but it has some quirks. Every time I unclick and reclick the menu, it resets to the default view rather than showing me the tab I was looking at before I unclicked the menu. It's a little annoying, but I can deal with it. I was hoping for a bit more customization of the menu as well in terms of determining what appears and what doesn't and in what order the icons go, but oh well.
I've changed the theme from the bland default "Air" to the more appealing (to me) "Oxygen". It looks a lot nicer now.
A new quirk I've found is that even though I've disabled these applications from startup, the applications Pidgin and Cairo Dock are still executed upon startup. I'm not really sure how to change this behavior now.
One thing I have done now that I didn't do before was to enable Activities. These basically enable me to keep Plasmoids (except for the panel but including the desktop background Plasmoid) on different desktops, greatly reducing the number of Plasmoids running at any one time. It's a neat feature, but I think only organizational freaks will find use in it.
I'm a little concerned that I can't really set default applications in KDE like I can in GNOME. It doesn't even give me the option of choosing Pidgin as my default IM client (it only gives Kopete as an option); the issue is similar with Firefox vs. Konqueror. Thankfully, OpenOffice.org is listed as an option for default applications.
Finally, I've found a quirk in Dolphin. For some reason, I can't permanently delete anything - I can only send it to the trash, which may not work if I'm deleting a particularly large file (like a Linux installation DVD ISO); it almost makes me want to use Nautilus again (and as I now know, in the newer versions of GNOME, Nautilus, like Dolphin, has split-pane viewing).
For all of these bright and dark spots, my opinion of KDE 4.3 is higher (but only by a little) than before. I'll probably be able to tolerate it a little longer than before - that is, before I get sick of it and decide to switch back to GNOME.
UPDATE: There are two things to update.
I got another weather Plasmoid. This one looks kind of nice, but still doesn't have a forecast.
More importantly, think of the devil... As I tried to use the "Lancelot" menu, it crashed. I guess it had to happen. Thankfully, that's the first time a crash has occurred since the start of this re-review.
UPDATE: Oops. Sorry I forgot this biggie.
For some reason even though KDE has a setting for power management, though I have set the computer to automatically suspend to RAM after 20 minutes of inactivity, this has never happened in KDE (though it faithfully happens in GNOME). I later did a manual suspend action and then resumed the session to find that suspending to RAM also logs the current user out of KDE. That explains a lot. It's a pretty big bug, though, as suspending to RAM can save a lot of power over leaving the computer on in full (even when inactive). A lot of people are used to this in Windows, and GNOME does it beautifully. KDE needs a lot of work in this regard.

Stuff I'd Like to See in a Future Linux Live CD

It should fit onto a Live CD.
I'm gonna start with the Linux Mint 7 defaults, and add/remove from there.
I'd like to see the default GNOME games included.
I want to see KolourPaint replace GIMP, as it is much closer to MS Paint (for new users), while GIMP's complexity can be a turn-off.
Instead of Eye of GNOME, use Okular and GwenView.
Instead of Nautilus, use Dolphin.
Add either Amarok or Songbird in the default installation.
Finally, add Wine.
I've tried making my own custom spin, but it hasn't worked. If anyone knows of a distribution like this or close to this, I'd love to know.

Review: KDE 4.3

The desktop environment (DE) that I've been using since I started using Linux is GNOME. Currently, with Linux Mint 7, I'm using GNOME 2.26. I really like GNOME for its simplicity, its lightness on RAM, its great collection of applications, its customizability, and its stability.
However, I took one look at some screenshots of the newly released KDE 4.3 (really, 4.3.2) and I was instantly smitten. I decided to try it out, so after configuring the proper repositories (the Ubuntu/Kubuntu 9.04 repositories don't have KDE 4.3, only KDE 4.2.2), I went ahead and installed it.
First, let's have some history (or, at least, what I remember off the top of my head; you can verify this information in Wikipedia by looking up the articles on "KDE" and "GNOME"). KDE was actually the first DE for the GNU/Linux project. It started around 1996 alongside the development of the Qt libraries. However, around 1999, issues arose over KDE using the non-GPL Qt libraries, so a group of KDE and Qt developers left and started GNOME and the GTK+ libraries.
Now comes the actual review on my 2004 Sony VAIO desktop with a 2.8 GHz Intel Pentium 4 HT (single core) processor, 1 GB RAM, and ATI Radeon 9200 graphics card.
My first impression after booting up and logging in (I haven't bothered to change the login screen from the default Mint 7 "Dew" theme to something more KDE-like) is that KDE takes a bit longer to load than GNOME; it almost takes as long as Windows XP on my computer. This may be because of KDE's higher level of polish and greater number of features, but in any case it is slightly but noticeably slower than GNOME.
Next, I played around with the Desktop a bit. The first startling revelation is that the contents of the Desktop aren't shown on the desktop; one must either open the Desktop folder in one's favorite file manager (more on that later) or create a nice snazzy Plasmoid (yes, that's the name for widgets in KDE 4's new Plasma desktop manager). The Plasmoids themselves are quite nice looking and functional, though the weather Plasmoid is rather lacking in information (it doesn't even have a forecast!). The way to access Desktop icons without opening the folder is to create a Lancelot Part Plasmoid and drag and drop the Desktop folder into the Plasmoid; this will create a permanent housing for the Desktop folder's contents. However, clicking on any file or folder in the Plasmoid will reopen the file manager rather than create a new Plasmoid.
I was intrigued by the new "Social Desktop" Plasmoid (one of the more talked-about features in KDE 4.3) until I found out that this did not mean that I could use Facebook from the Desktop without opening a browser. The "Social Desktop" is its own service (for KDE 4.3 users), while the Facebook Plasmoid itself doesn't work. That's a moderately large letdown right there.
The menu works very nicely; the layout is slightly different from the default MintMenu, but it is intuitive enough.
One quirk I found is with the virtual desktop management. For some reason, even if one switches to a different virtual desktop, windows in other virtual desktops remain on the panel. It doesn't seem buggy, but GNOME actually keeps applications minimized to a panel in a certain virtual desktop in that virtual desktop when the virtual desktop is switched. This greatly reduces the clutter on the panel.
One bug I did find was when KDE's panel (formerly Kicker) crashed on me twice on the same day. This is seriously buggy behavior and frankly unacceptable. I have never had a problem even close to this in GNOME.
One thing I like about GNOME is that it integrates Qt (KDE libraries)-based applications very nicely. Sadly, the reverse (KDE integrating GTK+ (GNOME libraries)-based applications) is not so true. Yes, GTK+ applications still work in KDE, but when running, they look like one is running Windows 95. It's a big disappointment aesthetically, considering GNOME completely carries over the Qt-look from Qt-based applications when running in GNOME.
This extends to even non-GTK+-based applications like Firefox and OpenOffice.Org. It's especially bad in OO.O as all of the icons turn into boxes of text, hiding half of the menu bars due to the long boxes of text. KDE probably wants one to use the native KOffice, even though this isn't even installed by default with KDE 4.3. Even worse, KOffice has much worse feature, font, and cross-product/file type compatibility support than OO.O. This is probably also why GNOME doesn't force AbiWord and Gnumeric on users by default except on lower-end distributions (and even then, AbiWord and Gnumeric have much better support for features and cross-software compatibility than KWord and KSpread). This isn't as much of an issue in Firefox, but GNOME integrates Firefox much better than KDE does. KDE probably wants one to use the native Konqueror browser (though it doesn't even come with KDE 4.3 by default), but GNOME doesn't usually require the native Epiphany browser like this; furthermore, versus Firefox, in terms of customizability and proper rendering of pages, Konqueror is on par with Internet Explorer 5 - it just isn't there.
One very bright spot is the selection of games (not real games, just diversions a la "Solitaire"). The selection of games is much nicer in KDE than in GNOME, and I would definitely play those just to keep myself busy for a few minutes when not doing something else.
The other, more important, bright spot is the file manager Dolphin. Nautilus (GNOME's file manager), take note. Dolphin has a lot more support for different types of viewing, like Mac OS X Finder-style split-pane viewing combined with tabbed viewing. It has a preview pane which allows one to really see a big (not tiny) preview of the document in question before opening it.
I will be keeping KDE 4.3 on my computer, but after spending a week with it, I'm ready to go back to GNOME. There are simply too many compatibility issues with non-Qt-based applications to continue with KDE, and the speed and stability isn't really what I'm used to from a Linux system. That said, I will still use Dolphin and all of the neat KDE games (in GNOME), but I will wait to truly switch to KDE.
