Abstract
Disclosed are a personal digital assistant ("PDA") and a method of providing data to the PDA. The PDA includes: (1) a chassis having first and second noncoplanar surfaces thereon and containing computer processing circuitry therein, (2) a visual display located on one of the first and second surfaces, the visual display coupled to the circuitry to allow the circuitry to drive the visual display and (3) a plurality of momentary keys located on both of the first and second surfaces and coupled to the circuitry, the plurality cooperating to form a chord keyboard to thereby allow multiple ones of the plurality to be depressed at a time to form a chord, the circuitry interpreting the chord as a single keystroke.
