No good...IMHO. Why would you kill the most powerful and portable notebook that Apple has? Don't blur the line between pro and consumer that much. iBook is consumer, PB is pro. Don't soup up an iBook if you want to do pro work, get a PowerBook. How many people honestly think the iBook
needs a better graphics card? And I'm not talking to the spec whores here, only those of sound mind.
And I really do think all the PBs will go through one more revision of the G4 before we see a G5 PB in January.
