I had Vista a while ago on my PC. The only reason I went back to XP was because it didn't have drivers to support my audio equipment and also didn't support my SCSI card for some reason. Also, when I get my mac, I will use the Mac for any devices that require drivers, and windows only for games, which Vista sucks for right now. Basically, there is really no reason for me to use vista with Mac, and I don't know what it would do for anyone. Until they get some decent drivers (especially video) then Vista is not worth it (and not even functional for many tasks).
