Next PowerBook to be superskinny

We still don't have any idea when Apple is going to come out with those new G5 PowerBooks everyone is salivating over (it seems like they've been having a lot of trouble getting those power-hungry, overheating G5 chips into a laptop), but we're hearing that whenever the next version does come out it'll be "considerably thinner" than the current ones. Probably won't be as thin as Sony's ultraslim
Vaio X505 (there'd be no place to put the optical drives,
for example), but a boy can dream, can't he?
