Gadget battles are won and lost on the price of components. In that regard, Sony has had poor luck with its latest PlayStation console. Its hulking size, exorbitant price, and dearth of interesting titles left it vulnerable to the Wii's unexpected rise. Gamers were more interested in the Wii's casual fun than the PS3's sophisticated Cell processor, especially since the available games hardly made much use of the expensive piece of gear. But the Cell is about to get cheaper. Manufacturer IBM has reduced the size of the chip to 45 nanometers, a technological leap which will at once make the processor cheaper and easier to cool, requiring a smaller case. Good news, at long last, for Sony.
