I've upgraded to XP, and everything seems to be working out.  I didn't have any problems with my video or sound, but i had to reinstall a few programs.  For instance, my G-Force 2 works fine, but i had to reinstall Adaptec(Burning Utility).  I think that the user inteface is pretty cool and i haven't had any problems with crashes or things like that.  I tried to crash my computer on purpose just out of curiousity, and all that happened was that i got an error in the last program that i ran, i clicked close, and XP kept running fine.  But you'll have to try it for yourself to know what i mean.
