Anyone on this list have a 12" PowerBook G4? How has it been in the areas of reliability, heat not causing problems, quality control, etc? I have a iBook G3 900mhz that has to be sent in again (2nd time, and the one year warranty isn't over with yet! At least I've got extended AppleCare and I've been getting lots of practice learning to backup with Carbon Copy Cloner). The iBook apparently has some quality control issues with the logic board, pinched wires and hard drives. I was considering the PowerBook G4 12" model at the time I bought the iBook, but then it was a bit out of my price range. I am considering switching to a PowerBook G4. I know the iBook is now comes with G4's, but it is too early to tell how they'll do in the "quality control" department...if they'll fair better, or worse than their 900mhz G3 counterparts, especially since the G4 is a "hotter" chip. The extended video desktop of the PowerBook is a nice feature that I'd like to have...I hear that the iBook can be "hacked" to gain this feature, but no thanks...Apple wouldn't appreciate that and would probably kill my AppleCare agreement.
