A bit about Orion, who hope to create personal supercomputers, aka cluster workstations.
I'm not sure if this is aligned with consumer needs in the long (long) term - I think it's the Net that needs to provide data crunching capability. That means real data crunch, not just simple database manipulation. Think about how difficult it is to build (or view) even a serious graph on the Net.
Of course, Orion's target market is professional users of scientific workstations. The problem is that this market is relatively small, and it's not clear whether global growth will happen. Still, it's big enough to make Orion a nice chunk of $$.
