1. A modular information processing system comprising:

  • an expansion device that embeds at least one internal peripheral without any controller for managing the flow of data to and from the at least one internal peripheral;

    a hand-held computer that embeds control circuitry including at least one controller for managing the flow of data to and from the at least one internal peripheral, and processing circuitry coupled to the control circuitry; and

    an interface for coupling the hand-held computer to the expansion device in a removable manner, wherein in a mobile operating condition in which the hand-held computer is not coupled to the expansion device, the processing circuitry controls the hand-held computer, and in an expanded operating condition in which the hand-held computer is coupled to the expansion device, the processing circuitry controls a personal computer formed by the hand-held computer and the expansion device.
