It is an amazing piece of hardware and it shows amazing promise - just trying to show people that Intel X64 CPU is about 200 Miles from a Cell, you can't compare!
How is it amazing? Its a good idea but it is far from an amazing piece of hardware. It offers little that a GPU can't already do. As said infact, Sony originally intended the 7 SPEs to handle graphics but it turned out to be pretty poor at this compared to a decent GPU.
In terms of FLOPS, GPUs from the last generation are significantly faster and are much more massively parallel.
In terms of general purpose computing, any CPU from the last 2-3 years is faster.

Isn't a to of the range core Duo like £700??
Also the cell would wipe the floor with anything when it comes to multi processor environments, which iirc is why IBM wanted it, so they could whack 50 into a mainframe.
It is superb at Floating Point operations which is what a lot of modelling software needs to do quickly. It is not to do with multi-processor environments.
Infact IBM is building the fastest supercomputer in the world over the next year or so by pairing 10k Opterons with 5/6k Cells. The Cells will basically acts as coprocessors with the Opterons handling the rest.

Well theirs 8 SPE's in total and one is kept for redundancy, so if you use another for OS then it leaves 6.
There are 8 in the Cell originally, but it was said that Sony only use 7 because their yields on the cores with 8 intact SPEs was too low. They therefore dropped the need of 1 SPE to up the yields of the chips. Not really for redundancy.
As said, another 1 is used for the OS but apparently it can be used if needed with some special coding.

They have already put it into some TV's IIRC, and IBM have started using it in some of their mainframe servers too.
The Cell was co-developed between IBM and Sony. IBM have been using it for quite a while. In fact rumour has it that IBM engineers were sent in to help improve Sonys yields.
