David: So, I Lied
This post is not from Windows XP.
However, I have just finished successfully installing it on my iMac. I need to track down drivers and stuff (wireless networks don't work well when the computer doesn't recognize the wireless card), but I will save that for another time.
I didn't do much with Windows but look at it and shudder.
I'm not sure it's going to get much use, but it's there now if I ever need it.
