The keyboard has a width greater than about 100 millimeters and less than about 160 millimeters, and each key has a width that is approximately 10 millimeters to 16 millimeters.

The keys are also positioned such that when the user places the device on a desktop surface, the user can type on the keyboard by conventional finger touch-typing.
