Since the G5 will likely not be in PowerBooks any time soon, and Freescale won't be sampling dual-core G4s until next year, the Freescale 7448 @ 1.8GHz/200MHz bus seems like a good bet for the next PowerBook revision. Do you agree? If so, when will this happen? (By September? This year?) By the way, does anyone know whether the 7448 takes full advantage of DDR RAM?
