RichardCarletta said:The eMac uses the 1.42 GHZ G4 already , so why risk supply problems using the same chip ? The Powerbook will probably be speedbumped to a 1.8 GHZ G4 by October. Not everyone can afford to buy a Powerbook , so I would expect a smaller volume of Powerbook sales compared to the rest of the Apple productline. If the iBook and lowend Mac Mini were speedbumped to 1.5 GHZ G4's in July , I suspect that Apple could immediately switch making Powerbooks with 1.67 and 1.8 GHZ G4's.
I imagine they're waiting until they can put the Freescale 7448 in the Powerbook, at which point the iBook will be updated to take on the specs of the current model of Powerbook.
The timing of the next iBook update depends largely on when Apple thinks they are likely to be able to release the first Intel notebooks. If they're a year away, and they only intend to release one PPC upgrade between now and then, then they could probably squeeze another couple of months out of the existing iBook and Powerbook models. We'll see.
