Vista is good if your computer is newer. i got vista for my computer, the only trouble i had was with my graphics card, it was an ATI Radeon 9250, which isnt supported by vista (yet) so i got a new one, but then i had to get a better PSU, but that was cause i upgraded the video card over the 250watt limit of the original.
Other then the high system requirements, its a great operating system.
