Abstract:
1. A portable computing device including a housing having a top surface and a bottom surface connected to one another by a pair of sides, a proximal end and a distal end, the top surface including a user interface for operation by a user, the device comprising: a planar surface located on the bottom surface at the proximal end, the planar surface extending to either side of a centerline of the housing and in a direction towards the distal end, the planar surface defining a plane, the centerline extending in a direction between the proximal end and the distal end; a first protrusion located on the bottom surface at the distal end, the first protrusion extending between the bottom surface and the plane, such that the first protrusion has a peripheral surface lying on the plane on one side of the centerline; a second protrusion located on the bottom surface at the distal end, the second protrusion extending between the bottom surface and the plane, such that the second protrusion has a peripheral surface lying on the plane on the other side of the centerline; wherein the first protrusion, the second protrusion and the planar surface provide stability of the device when placed on a surface adjacent to the bottom surface, the stability facilitating operation of the user interface by the user, and wherein the planar surface is provided as a raised rim around a periphery of at least a portion of a bottom surface of a power source cover, such that the rim has a peripheral surface that defines the plane that is in common with the peripheral surface of the first protrusion and the peripheral surface of the second protrusion.
