Is there any rumor afoot regarding the use of the 1.25 GHz G4 in powerbooks? Or any reasons why its not going to happen(e.g., too hot [I have no idea how hot it runs], etc.)? It seems like the extra cache size, if not the extra 250 MHz, would really help make the PB even more of a desktop replacement. Are the rumors that we're high centered with the current processor until the 1.2 GHz 970 comes along? Does Apple feel like they've addressed the notebook folks for awhile?
