Toshiba doesn't want us to forget that it -- and IBM -- shared development of the Cell processor; Toshiba intends to beat Sony with the first non-PS3 device to use the chip. Toshiba hasn't announced a specific product, and speculation in a Macworld UK article
suggests that it may be 2008 before any new device uses the chip. However, the video-related horsepower of the processor lends it to TVs, DVRs, and other home-entertainment devices.
We hope the Cell becomes common in many products; the increased production could drive down costs, eventually cascading to a PS3 price cut. We can dream.
