Greg Joswiak, Apple’s vice president of hardware product marketing, told the BBC today that a PowerBook using the PowerPC G5 processor is still a long way off. “The G5 is part of our long term processor roadmap, but it will be some time before that processor will be in a notebook,” he said. As previously reported, Apple engineers are working on reducing the heat generated by the chip before it can be incorporated into the laptops. Joswiak pointed out that it had taken at least two years for the G4 chip to make it from the Power Mac to PowerBook.
