With all the PPC 970 Powerbook rumors floating around, people have been talking about not getting the Rev. A powerbook and waiting for the Rev. B instead... my question is this: Have there been any bad revision one powerbook or any other apple products? Everyone talks about "ironing out bugs"... but really, what bugs are they talking about? Adding new features? I personally expect a 100% functional product, even Rev. A... am I missing something? Thanks.
