My Two Cents:
The only reason the iMacs swivel screen works is because the dome weighs it down.. I doubt that there would be a tripod section.
No speed bumps in the iMac... Are you crazy? People complained how the iMacs were infecting the turf of the towers, theres no way they'll do anything to them now, or they'd be at almost-tower-speeds again.
A new digital device would be nice, and it's quite possible... Im not quite sure what, but there are plenty of other people with guesses.
Upgrade in the TiBooks, maybe a little faster clock speed. No dual processors (that will never fit) and no super drive (way to big and way too expensive)
No iBook or tower bumps.
I'd like to see a 19 inch monitor, but I'm not sure... I do know that most people would like atleast a 17" monitor though...
iMovie 3? possibly. iPhoto 2? no, but maybe with a few bug fixes. Another update for OS X, likely.
Most of the time I think though will be spent demonstrating the new towers in head to head competitions with peecees in photoshop tests, since steve-o didnt get to do any at the last expo.
That's my opinion... don't hurt me. 😉
