Ive stuck it on my pc (Ultimate AGAIN!) to play with. now under xp games like crysis played fine! under vista loading times are longer, the game is so slow and the sound is skipping like made its not playable.
users account control is annoying as it pops up every time you need to do something! turning it off also means that you get pop ups every few mins and reboots telling you that its off and needs turning back on.
It looks nice areo glass is good, but finding programs in the new start menu is hardwork and its annoying.
