ABSTRACT:
A computer system which is reconfigurable to provide separate ergonomically advantageous positions for keyboard input and for stylus input. A primary system chassis contains a bay in its underside where a detachable keyboard can be stored. For one-hand stylus input, the keyboard is left in its bay while the display is mounted flat on top of the system chassis. For keyboard input, the keyboard is mounted on the system chassis, and the display is supported at an angle which makes it easily visible to a user typing on the keyboard.
