Cell chip makes laptop debut in Toshiba Qosmio... but why?
 

The PlayStation 3's Cell chip has made it a lot further out of the console niche than did the Emotion Engine that powered its predecessor, and for that, I credit IBM's cleverness in getting Sony to fund the purchase of a supercomputer coprocessor that could also be pressed into service as a game console chip. Cell is a fantastic fit for highly parallel, floating-point intensive supercomputer workloads, which is why Toshiba has formally announced a Cell-based laptop... er, wait a minute. A laptop?
