If Wristers claims can be taken a face value, Motorola's implementation of low-k dielectrics, with its implications for major power consumption reductions, make it a strong contender for PowerBook - and possibly iBook - processors going forward. Curiously, Motorola's announcement that 0.13 micron parts with low-k dielectrics will appear within weeks comes not only just ahead of Apple's Worldwide Developers Conference (WWDC), but hot on the heels of major price cuts on Apple's 12in and 15in PowerBook models. Price cuts are typically a signal that models are to be refreshed.
