Question: Was it Windows XP Home Edition, or Pro? if its pro, there have been bench marks that have it with nearly 30% higher performance rating than Windows 2000. I never believe the results of just ONE test. For me, you have to provide several different tests along with hard core evidence. I want to see it for myself. I'm on Win2k and I wouldn't go to any other OS. Its stable, easy to work with, no stupid ALT(Command on a mac) things to learn like Linux and Mac, its decent looking, doesn't look like a hippy puked on it, and it runs all of my apps at the same time without a problem. All this on an AMD 1.0ghz T-Bird that is OC'd to 1.25 . Go fig.
