It's not a notebook. It's a hybrid between a desktop and a notebook. I already have a MacBook and MacBook Pro, so I'm itching to see how it all works out.
It'll be interesting to have Mac OS 10.4, Mac OS 10.5, Mac OS 10.6 along with Windows XP Professional working on the same network running simultaneously. I'm really not sure how I'll be able to work this out, to be honest.
