XP is a lot sleeker then I expected. The stock colors are kinda gay and they're the first thing I changed. The second was the start menu.. too cluttered... third was the grouping feature on the task bar.. too annoying using AIM and multiple MSIE windows.. Besides those things, it runs just as good as 2k Pro, but is a lot more user friendly. I can tell many things are based on 2k Pro just by looking at it. I must add that it was a quick and painless upgrade, compared to 2k being like loosing your mouse and having to type everything in. Must easier on the install So far I'm happy with it. Also shuts down and starts much faster.. something that is always good. Anyone else have it and wish to share?
