Cell is an architecture for high performance distributed computing... According to IBM the Cell performs 10x faster than existing CPUs on many applications... The Cell architecture can go further though, there's no reason why your system can't distribute software Cells over a network or even all over the world. The Cell is designed to fit into everything from (eventually) PDAs up to servers so you can make an ad-hoc Cell computer out of completely different systems.
I've read indications that Linux has been ported for the architecture. :-)
