What's next for Apple notebooks?
Given Apple's public statements about the G5 in a PowerBook, I would venture to say that the next PowerBook will feature a 1.8GHz PowerPC 7448 from Motorola/Freescale. I know, I know. The speeds of the supposed 7448 have yet to be discussed, but I am assuming that because the iMac G5 is at 1.8 GHz, the PowerBooks will attempt to match the clock speed, albeit it will be a G4 processor and not a G5.
I think the next rev of PowerBooks will be the first to sport 100GB hard drives.
I don't know if an enclosure modification or complete make-over is in the works, but the current crop of aluminum clad PowerBooks have been around since January 2003 _closing in on two years. Rumors of carbon fiber have been floated for quite some time mostly from Mac OS Rumors. So who knows how true this is!
Regarding the iBooks even longer still their enclosures have remained relatively the same since they were released on May 1, 2001. I would expect both lines would receive a cosmetic make-over.
Which brings us to the when. I think it's a crap shoot at this point. I would say anywhere from the last week of September (when a promotion with PowerBooks ends) to MacWorld SanFran in January. The later we wait for an update, the more and more the liklihood that they will be getting a major redesign at MacWorld in January.
