Abstract
A keyboard for a hand-held computer. In one embodiment, the keyboard includes first and second portions that are removably coupled to each other. The second portion can be removably coupled to one part of the first portion to block access to input keys of the first portion, and can be removably attached to another part of the first portion to allow access to the input keys, forming a full-size keyboard for a hand-held device. The second portion can be reversible to allow access to input keys on either a top or bottom surface of the second portion, and can also be pivotable relative to the first portion about an axis that is generally perpendicular to an upper surface of the first portion.
