Sure, you probably don't currently have a need for 256 gigaflops of processing power in your home. Rest assured, you will -- just as certain as the day when robots will care for our children and decorate our Christmas trees. So go 'head, raid the education fund and future proof your domicile by picking up a TYANPSC T-650 series computer from Tyan -- "PSC," as in Personal SuperComputer. Prices start at just $20,000 for a 40 CPU Core (10x quad-core Intel Xeons) system configurable with up to 60GB of RAM and a power draw of just 15A. And it's "portable" in the same way a refrigerator is portable: it has wheels. Who knows, maybe you can put those spare cycles to use by solving the traveling salesman problem.
