Basically this keyboard is held with two hands and your fingers go across the back of the device. The keyboard keys are on the back of the device, rather than the front, giving you 4 fingers for typing and dedicated mouse controls. These are on pre-order for $60.
Might not be the revolution in HTPC controls that we need, but its nice to see people trying to build new/novel keyboard concepts for HTPCs.
