John Gruber from DaringFireball got it 100% right. My predictions were not too bad either, but he was just spot on.
The main thing here is the change in manufacturing process. They are leaving a lot of things open for the future. I personally like the choice of the Mini Display Port instead of an HDMI slot. HDMI is a secured architecture that requires you to pay royalties and is basically created just so that applications have permission from the MPAA to play your content. I am not a fan of this. Apple is basically marking a line in the sand, saying computers are here, media centers are there.
Like always leave it to Apple to not try and do a all-in-wonder product. That is why I like them. My new MacBook Pro will be here next week and I can't be any more excited. I recommend you step by Daring Fireball and read Gruber's post on why Apple didn't release a $899 laptop, its worth the read.
