Install Windows XP on it!
Along with OSX of course. But do it. Just because it's apparently possible after all.
I think that's still a hoax (if that topic is the iMac-cum-Windows XP 64bits edition one) since there's quite a lots of thing in the video that are out of place.
I'd like a MacBook Pro but I brought the latest PowerBook G4 15inch a couple weeks ago before Apple took them aways, why? a lots of reason, one is that I'm a pro user which should answer your question.
thought I'm looking forward to the rumoured 13.3inch MacBook Pro, Windows Vista and OS X in one laptop? a dream come true!
(Windows Vista's boot under EFI)
