Abstract

The present invention is directed to a handheld electronic device comprising one or two modules operatively interconnected via a pivotable connection mechanism or other moveable mechanical interconnection. Each module has two surfaces facing in opposing directions. The device further comprises a first display carried by a surface of a module, and possibly a text-entry keypad provided on a different surface. The text-entry keypad is optimized for entry of text via thumb-keying styled text-entry, wherein the user's hands cradle the device so the thumbs are in proper position for operation of the keypad. A navigation control may be provided on a surface of the module, and is sized and positioned to be operated by at least one finger or at least one thumb of the user's hands when cradling the device. There may also be provided for handset use, a second display sized substantially smaller than the first display, as well as a numerical entry keypad, an audio output port, an audio input port, or selective ones of such devices. These components can be provided on the surface of one of the two modules, such that these types of components remain uncovered and accessible in various configurations of the device.
