I have 2 personal work boxes at work, one is my 3 year old P4C 2.6 running XP, and the second one is a brand new and shiny (well, at least it was in december) Dell tower on which I installed Vista last December... Needless to say, the Vista box sits there in the corner, and I barely use it... My professional tools do not work with it, even Microsoft's own VS / TFS runs only with a half-assed broken beta patch that crashes every few hours... About the only thing I do on the box is play FPS with my co-workers, as conroe + crappy ati card >> p4c + even crappier (even by 3 year old standards) graphic card...

So yeah.. Avoid Vista for now.. Ask yourself - what does Vista do for you that your XP can't?? And if it's for the "eye candy (which is very limited and annoying at long run), get yourself al inux distro and install Beryl on it - it jumps hoops and runs loops around Vista's Aeroglass.
