Patent ID: 8072423

Claim:
A digital computer having at least one display for displaying information, comprising: a) a housing having at least one front surface, facing a user viewing the display, side edge faces and a rear surface opposite to the front surface, b) an input device having input means on at least one surface for at least one of inputting and manipulating information, the input device being an input module, c) a coupling bay which receives the input module so that it can be reached from at least two sides, the input module being movable from a position accessible at the front face of the computer with respect to the housing to a position in an oppositely facing orientation by removing the input module from the coupling bay and inserting it into the coupling bay in the oppositely facing orientation that enables the inputting or manipulating of information at the rear surface of the digital computer housing instead of at the front surface of the computer housing, and is electrically connected to the digital computer via at least one interface, said input device also being operable for inputting or manipulating of information in a decoupled state disengaged from the housing wherein at least one of the coupling bay and the input module is provided with at least one further interface for use with said oppositely facing orientation.
