One embodiment in accordance with the present invention includes a nested flip cover lid for a portable computing system such as a personal digital assistant (PDA). Specifically, the nested flip cover lid includes an accessory rail spine, a hinge and a rigid material that is fabricated to nest within the top cover parameter bevels surrounding the display device of the portable computing system. Therefore, the nested flip cover of the portable computing system is designed and fabricated in order to add a minimal amount of thickness (e.g., 1 millimeter) to the overall portable computing system package. Furthermore, the nested flip cover may also be integrated with a latching mechanism in order to secure the nested flip cover closed when the portable computing system is not being used. In this manner, the latching mechanism keeps the nested flip cover aligned with the outer parameter of the portable computing system.
