Abstract: A portable computing device comprises a first body portion, a second body portion and a hinge connecting the first body portion and the second body portion. An antenna for a radio frequency transceiver is placed in a vicinity of the hinge.

Abstract: Techniques for overlay surfaces for compute devices are disclosed. In one embodiment, an overlay surface on a base portion of a compute device can be moved from a folded or closed position (in which it does not cover the keyboard) to an unfolded or open position (in which it covers part of the keyboard). The base portion includes a touch sensor that allows the overlay surface to be used as a touch surface. In another embodiment, an overlay surface of a compute device is movable from one position adjacent a display of the compute device to another position adjacent a base of the compute device. The overlay surface is electrically switchable from a transparent state to an opaque state, allowing the display to be seen through it in one position and allowing it to be used as an opaque drawing surface in another position.
