The PowerBook G5 Myth
There's a fake press release making the rounds (it has typoes and it's wording's wrung, so yes: It's a fake...) about a PB G5 being released on Tuesday (and yes, Steve would announce it on Monday at the WWDC keynote, of course...).
Still: There are some myths around a possible PowerBook G5 that many people - including me - don't quite understand.
For example, the PB G5 should be the "mother of all thermal problems", Apple said in the past. And said it again when they released the last round of yet-another-G4-PBs. Yet: If you look at FreeScale's and IBM's power/heat numbers for the processors as well as what intel/AMD notebooks dissipate, it seems not only perfectly feasible (at a bit less than 2 GHz, that is), it's even almost not understandable why Apple hasn't done it in the past! Unless, of course, Apple plans to move to intel chips with the PBs first, so they could always claim that the PB G5 was "the mother of all thermal problems" and therefore couldn't be done, anyway. One more reason for a great marketing speech on Monday by Steve Jobs? We'll see.
However: I really don't expect a PB G5 on Monday. Or Tuesday. Or in a week. But then again: The rumour world was awfully quiet in the past weeks, and this certainly doesn't mean that Apple isn't working on hardware at all, it just means that people have become more careful after Apple's recent threats and lawsuits.
