Granted, I went overboard when saying XP was a better release in the beginning, probably due to the fact I was hoping for a better RC1 for Vista. Also, be warned that my POV is stricly based gaming wise.
Although, I'll stand by my word when saying XP is a better system (at the moment) and Vista isn't worth the change. I do understand drivers are constantly released, which is why in the meantime, I'll simply wait.
That being said, unless Huxley hits the store this june and is Vista compatible (enhanced via DX10), I hardly see any reason for such an early switch.
Also, for those interested,
here's a list of compatible games for Vista.
