Abstract
A peripheral input device having a body configured to be stored within a housing of a computer device is disclosed. In at least one embodiment, a wireless input device is configured to be recharged within the housing. Further aspects of the invention relate to an input device configured to operatively connect to underutilized ports of a computer system. In one embodiment, the input device operatively connects to a PCMCIA port of a computer. Yet further aspects of the invention relate to an input device having an expandable body, wherein the body may be configured to have an increased surface area upon expansion of the body.
