A lid has a planar front face corresponding to the upper extent of the front surface. The front face terminates in a front free edge. The lid has a rear face corresponding to an upper portion of the upper extent of the rear surface. The rear face terminates in a back free edge. The lid also has a periphery. The periphery includes a top with sides. The periphery terminates at an angled edge. A hinge couples the back free edge of the rear face of the lid and the back surface of the device in proximity to the forward edge. In this manner the lid is adapted to pivot to a closed lower orientation to cover the buttons and an open raised orientation to expose the buttons. |
