I used to be really down on the XP version until I upgraded my father's computer to an AMD XP1700 and none of his games worked on the ME system. I still have no problems running ME on mt xp1800 AMD chip. But I have also seen some great performance from his machine. I still have some issues with XP such as not being able to install it on the same machine more than four (4) times I upgrade so often. But it is far more stable than any version of windows that I have seen thus far (and I've been using PC'S since before windows was even a wet dream for Bill.)
