An improved body design for a mobile station or other electronic device is provided. Unlike conventional mobile station bodies, which are comprised of durable polymer shells that are rigidly joined together (e.g., by ultra-sonic welding, adhesives, etc.) to enclose operational elements and circuitry, a replaceable and enhanceable body structure comprised is provided that is comprised of one or more stacked elements. The stacked elements are positioned one atop the next in a facing relationship. In one embodiment, the stacked elements define one or more apertures for receiving and enclosing one or more operational elements (e.g. a display, a keypad, an antenna, a mobile station engine, etc.).
