Vista 64 bit works smooth as silk on my art rig :)
in 64 bit, with 8 gig RAM, it's a pussycat.
It's more stable, easier ot use than XP Pro is.

Note: XP Pro 64 does not have a lot of drivers for things, which causes problems.

Vista, on a recent PC, with Intel CPU, 2+ gigs RAM (minimum!) and Nvidia gppahics card, seems ot work very well.
It is a memory hog, but the larger your system RAM the less problem this is.
A laptop with 512 can barely function with Vista, and is just "acceptable", IMHO, at 1 gig.

I have odd bug with a Photoshop plugin in Vista 64, that's it.
Oh and they don't make Registrey Mechanic in 64 bit version, pity, awesome app for keeping XP working ok!

Each to his own though! :)
