Abstract
An improved methodology and implementing system are provided in which a display device is selectively converted by a user to change its processing configuration from a first mode which suitable for use in a first computer environment, to a second mode which is suitable for use in a second computer environment. In an exemplary embodiment, a display device is configured to also act as a touch-sensitive input unit to provide user input in a hand-held computing system. The display device is further enabled to be converted for use as the display in a laptop computer system with a keyboard and/or mouse input. Each configuration has a separate bus and includes a separate CPU. A common display device and palm unit non-volatile memory are accessible from either configuration. A user is enabled to input a selected mode of operation and configuration for the display device through a selection switch on the display device. In an alternate arrangement, the selected mode of operation is automatically determined by internal programming designed to detect the type of device that is connected to the display.
