I once worked with a QA guy who I thought of as a dinosaur...
I worked at NASA for a while, and it was interesting seeing the ancient artifacts from the Golden Age tottering around. Not that they weren't perfectly fine people, they may even have been doing somewhat productive work. A couple even reminded me of dinosaurs. Or at least actual fossils.
Anywayz, having tried all the new and upcoming Microsoft products, including Silverlight 4 beta, I'm going back to Linux. (Sure, I'd rather be running a BSD-licensed OS, but they suck even worse.)
I put Win7 on the laptop I retired from daily use over the summer, due to repeated hardware failures. Basically, I wore it out, even though Linux on the 2.8GHz P4 (ca 2003) still screamed. And I'd been looking for an excuse to get a multi-core system for a while...
Anyway, just sitting there, Win7 will put the disk into serious use for 5-10 minutes out of nowhere, even if it's just sitting there without being used and with no applications running. I have NOT installed anti-virus or any of the other crapware. Leaving taskman open, CPU usage goes to 40-50%, disk lights flashing, and nothing running. Strange.
I don't like the Linux desktop, but hey - it's home. Kissing Stallman's government-loving butt and having to run a mixture of GTK, Qt, XUL, Java, and Wine applications isn't so bad... really... 
Never having kissed Stallman anywhere, I can't say. I'm not a beard man.
If I may ask, since KDE can be made to look/act much like the traditional Windows interface, what it is you don't like? Is it just the mix of GTK, Qt, Java, etc, or is it "look and feel"? I've noticed that much use of Windows now cannot be done without that "mix" of Java, etc, either.
