A wireless communications device, such as a cellular telephone, includes first and second bodies having respective perimeters. A display is associated with one of the bodies and user input is associated with the other. A hinge mechanism moveably couples the bodies together so that the second body may pivot between a closed state and an open state. The second body, while in the open state, is slidable from a first open position to a second open position along the perimeter of the first body. The first and second bodies may have respective major axes, and the major axes may be substantially parallel when the second body is in the first open position. The major axes may advantageously also be substantially parallel when the second body is in the second open position. The bodies may include respective peripheral slots along which the hinge mechanism moves.
