Just think we will all be able to have supercomputers running Linux sitting on our desktops. ;D That is as long as we don't suck them up in the vaccum cleaner. ;D :P
Today's R&D is focused on processors no bigger than a grain of sand. The enabler is nanotechnology: systems for transforming matter, energy, and information based on nanometer-scale components.
To reach grain-of-sand status, researchers at Georgia Institute of Technology, Atlanta, have demonstrated binary optical storage using nanoclusters of silver oxide, two to eight atoms each.
