I've run Vista in BootCamp and run it on my gaming PC, and have had no problems with either one. Of course, I know what i'm doing. 
It requires more tweaking than XP to get it useable from a power-user perspective, but everything thus far has "just worked" for me.
The only thing I honestly don't like about Vista is the lack of new sidebar gadgets. It's been out for over a year, and there is still no decent GMail gadget.
I'm still sticking with Leopard as my primary OS, and would ditch Windows altogether if Apple made a mid-range Mac suitable for gaming, but until then I'm perfectly fine with running Vista on my game system.

and the NAME. It was not anything new, it was soo hyped up, if you ever read anything after XP came out, the new OS was supposed to change the way we use computers. The 1st comment is correct, its like 98 and ME same feel different name, and you have to pay for it.
