A tablet computer comprising:
- a tablet computer housing;
- a first display panel set within said housing;
- a keyboard overlying said first display panel, said keyboard comprising a plurality of key mechanisms, each of said key mechanisms comprising:
- a key cap, said key cap including a first portion that is substantially transparent, and a second portion that is not substantially transparent;

A tablet computer comprising:
- a tablet computer housing;
- a flexible overlay substantially coplanar with a top surface of said tablet computer housing;
- a matrix structure positioned beneath the flexible overlay, the matrix structure defining a plurality of cavities and being comprised of a substantially transparent material;
- a display panel underlying the matrix structure, the display panel operable to display a key symbol beneath each of the plurality of cavities;
- a plurality of optical emitters oriented to transmit light beneath and parallel to the flexible overlay;
- a plurality of optical detectors beneath the flexible overlay, each of the optical detectors positioned to receive light emitted by one or more of the optical emitters;
- whereby downward deformation of the flexible overlay can act to interrupt the transmission of light between one or more of the optical emitters and one or more of the optical detectors.
