I have AMD XP Pro on a desktop I use strictly for a server. I would like to venture away from M$cro$oft, strictly because Windows has been falling ever since 2000. XP is a nice OS, but Vista...come on??? Why on Earth is it necessary to create a "virtualstore" in each user name...UAC....? WTF were they thinking? All UAC proves is that if you dont pay good ol' Bill Gates enough money to be on his approved software list, he will make sure that everyone knows how "bad" your software is. Thanks for all the tips guys; I think its awesome that some of you run OS X on an intel machine...I'd like to try that one!
