ABSTRACT:
Portable electronic devices, such as personal computers, are provided by this invention which include hinged housing compartments containing a monitor and a keyboard as well as at least one extendable flap for extending the keyboard surface to more closely approximate a full size keyboard. These devices are much easier to type on and do not sacrifice functionality of compactness. Extendable supports are provided to retain the flap in a substantially planar orientation.
