Vista/7 has a lot of advantages over 2000 and even XP. Ignoring the eye candy, it's little things that I like, such as being able to update graphics card drivers without restarting the PC. Sure, it's not something one does every day but it's nice to know it's possible. The audio architecture is considerably better in Vista/7, even though they remove DirectSound hardware acceleration. Native AHCI support is nice, even though it doesn't usually show in benchmarks. EVR video renderer almost makes up for the **** up that is VMR. I'm not saying that 2000 is a bad OS, but there are a lot of useful features in later OS and on newer hardware, Windows 7 probably runs "better" overall than Windows 2000.
