Abstract
Abstract A versatile device is obtained with a PDA that includes means for cordless connecting to specialized accessories. The PDA can operate in its conventional mode, or it can be enhanced by interconnecting it with some or all of its accessories. In one embodiment, the PDA is combined with a cellular telephone that is adapted to physically mate with the PDA and form thereby a single integrated apparatus. In another embodiment, the PDA is combined with a landline telephone that is adapted to mate with the PDA and form thereby another single integrated apparatus. In a still another embodiment, the PDA (whether or not mated with a telecommunication device) is combined with a keyboard to form a laptop computer.
