Macnn reports that the US Patent Office published Apples patent application entitled Keystroke tactility arrangement on a smooth touch surface. Descriptions and claims clearly indicate that it could be the basis for a full multitouch keyboard. If such technology is perfectly used for the iPhone and the iPod Touch, it could not be used as such for a LCD panel or for a desktop computer. However we could imagine that a multitouch peripheral could be used instead of a keyboard, providing all functions of a mouse, keyboard and trackpad in a single device
