A computer peripheral connects to a host computer such as a PC to assist in a presentation. The peripheral includes a memory and receiver combined within a portable, lightweight housing. Presentation data is stored in the memory, while the receiver receives wireless signals from a handheld transmitter for paging through slides or other segments of the presentation using page up and page down instructions. The memory may be a USB hard drive, for example, or other portable storage media. The peripheral is connected to the host computer using a USB cable and an externally-accessible port in the housing, for example. A hub controller within the peripheral enables the memory and receiver to communicate with the externally-accessible port, thereby providing communication with the host computer.
