Windows XP on my IMac
It seems I bought my IMac at just the right time. Not only can I get all the Mac Benefits of video / image but now I can run Windows XP on it as well using the public beta Bootcamp! :)
Impressive.... I have yet to see if I can get Flight Simulator running ;)
EDIT:
Well, FS is installed and works with good performance! :) Excuse the crappy picture, flash etc... but it gives you an idea.
