I got a new pc with vista when they first came out, over a year ago.
Not really had any problems , apart from finding some programs that will run on vista
i did run xp and vista on 2 pc's that were exactly the same and vista needed a reboot less than xp
after a couple of months i shut down the xp pc and sold it lol
We have 2 laptops and one pc now and all are running vista
