Any word on the kind of processing power this thing is? It really does sound like the future, with it's supercooled processor 'n all. They state the price is "consistent with large-scal,high-performance computing systems" whatever that means, could it possibly be worthwhile?

Which makes it quite usable, to my suprise. In 30 years I'll have one at home. Not to worry. Best regards, Lodewijk 2011/5/27 James A.
