What do you think will be the iBook proccessor when the other computers get a PPC 970? Continued G3 speed bumps? Would make sense since the G3 can be bumped to at least 2 GHZ. A G4? It might not be a good mobile chip but with the other computers getting the powerful PPC 970 chip the G3 proccessor may become obsolete as it is underpowered. And thus won't be able to run the software that will come out optimized for PPC 970's at all. Or maybe a low clockspeed PPC 970 Mobile proccessor? What are the odds of that? A mix between the pwoer of a 970 and mobility so it will not get too hot etc.
