Abstract
A mobile computer may comprise a notebook computer base, a transparent Liquid Crystal Display (LCD) configuration, and a removable multi-function wireless digitizer tablet. A notebook computer base may contain electronic components that can store, retrieve, and process data; and wireless communication circuitry. A transparent LCD configuration is comprised of a liquid crystal display (LCD) panel having preset display characteristics, such as image brightness and contrast. A removable multi-function wireless digitizer tablet may comprise a digitizer tablet; wireless communication circuitry; a magnetic stripe reader, batteries, various types of cameras, an enclosure, and mobile computer navigation/control functions.
