What is claimed is: 1. An adapter unit that communicates with a personal digital assistant (PDA), comprising: a carrier portion that includes two sidewalls and a bottom wall that conform to a surface of the PDA, at least a portion of each of the two sidewalls are curved to partially encompass at least a portion of a display-side surface of the PDA; and a product identification reader that is encased in the carrier portion and reads a product identification code. 2. The adapter unit of claim 1, further comprising an expansion connector that facilitates a communication link between the carrier portion and the PDA. 3. The adapter unit of claim 2, the expansion connector facilitates the communication link between the PDA and the product identification reader. 4. The adapter unit of claim 1, the carrier portion further comprising at least one of a radio, a CCD imager, an RFID tag reader, a global positioning system technology, and a telephone. 5. The adapter unit of claim 1, the product identification reader is included between a cover and a bottom wall of the carrier portion. 6. The adapter unit of claim 1, at least one of the sidewalls is curved to conform to the PDA. 7. The adapter unit of claim 1, the sidewalls only partially cover respective surfaces of the PDA. 8. The adapter unit of claim 1, further comprising circuitry that facilitates wireless communications. 9. The adapter unit of claim 1, further comprising a gripping surface that extends above a top section of a bottom wall of the carrier portion. 10. The adapter unit of claim 9, the gripping surface comprises more than 20% of the length of the PDA. 11. An adapter unit that communicates with a PDA, comprising: a carrier portion that includes two sidewalls, and conforms to at least a portion of a front surface of the PDA, the two sidewalls are overlapped by a wall portion of the adapter unit; an expansion connector that facilitates a communication link between the carrier portion and the PDA; and a product identification reader that reads a product identification code, and is encased in the carrier portion between a cover and a bottom wall of the carrier portion. 12. The adapter unit of claim 11, further comprising a battery door that facilitates access to a battery. 13.
