I have vista and personally I hate it. Half of the programs I use [I tune high performance cars on the side] have to be ran under XP SP-2 emulation. The vista OS uses over 400mb ram just in itself. I'm going to be buying a laptop with XP pro installed at some point down the road and staying away from vista until I have to upgrade.

The version of vista I have is Basic, so there arent any of the other frills that use even more of the system resources if that tells you anything.
