IBM has done it, Compaq (Alpha) is in the process of doing it, AMD has announced
plans to do it. Intel is evidently too muddleheaded to make "the right choice."

Because you have to connect the CPUs to the rest of the computer somehow, and
this is pretty much impossible when it's in wafer form. The other problem is
heat.

Because the Kryotech equipment is bulky and noisy and basically just awkward.
