Bad Experiences are Forever

This is a sort of follow-up and is opposite to the previous post. There are a couple things that I had bad experiences with that I should probably try out again; these things have probably left worse impressions on me emotionally than rationally.
First is Toyota. Toyota has had a rough couple years, starting with issues of premature rusting in its trucks' frames and leading up to the "unintended acceleration" fiasco. Through it all, it's managed to become #1 in sales, but this too has come at the cost of its quality; now, the parts it uses especially in the interiors of its cars are flimsier and aren't assembled with the same attention to detail as before. My family owned a 1988 Toyota Corolla, and it ran beautifully until 2004; it was solidly built, and the attention to detail was striking. Now, no more. That said, the unintended acceleration fiasco (which pushed my skepticism of Toyota over the edge) is finished and its new cars are pretty solidly built and competitive, so I really shouldn't instinctively turn me away from all Toyota products (though I'd still rather wait a few years before recommending their products to anyone again).
Next, Fedora. I tried the Fedora 11 "Leonidas" GNOME live CD about a year ago, and I loved it. I really liked the fact that it, unlike Linux Mint 7 "Gloria", detected all of my hardware out-of-the-box (including my graphics card and monitor at its native 2048 by 1536 resolution). So I decided to install it. That was a terrible idea: not only did it fail to install properly, it also managed to mess up my existing Linux Mint 7 partition at the same time. I tried again, and it still didn't work. I then decided to hold off until the next release. Version 12 "Constantine" was worse; no live CD or live USB I created (the usual way) would boot. That's when I gave up on Fedora. That said, just about a week ago, I and a friend of mine (who is a Red Hat/Fedora guru) installed Fedora 14 "Laughlin" GNOME on a mutual friend's laptop (which was suffering from a slow and malware-ridden installation of Microsoft Windows 7). The installation itself worked flawlessly, and aside from multimedia codecs (which was easily fixed through the handy program Autoten), everything worked out-of-the-box — Skype (i.e. webcam and mic), printing (and scanning), desktop effects, etc. Given this, I really shouldn't hesitate, yet I still do. Maybe it'll happen when Fedora does actually support NVidia's Optimus technology.
Finally come laptop touchpads. Wait, no — those are ergonomically inferior to external mice. Whoops! (Heh heh.)
