By Larry Angell – All of the key components for Apple to produce a PowerBook G5 appear to be ready, and Mac users should expect to see the new laptop no later than this summer, Peter Glaskowsky, analyst with Instat/MDR and editor of the Microprocessor Report, told MacMinute. He noted that the IBM PowerPC 970FX—which is used in the Xserve G5—offers basic power-consumption features needed for a portable machine. Glaskowsky explained that the 970FX also has PowerTune, IBM’s version of the voltage and frequency scaling technology used on x86 laptop processors. “With all this new technology, a PowerBook G5 should be much faster and last about as long as a PowerBook G4 in average usage,” he said.
