Keyspan has announced the release of its Presentation Remote Pro, a Radio Frequency (RF)-based remote control for the Mac. it costs $79.
The device works up to 100 feet away from the host computer, and features a two-button mouse, laser pointer and audio controls. It works using a separate receiver that plugs into an available USB port on your Mac; when not in use, that receiver can be stored directly within the remote.
The Presentation Remote is plug and play. No software is needed to set it up or to use it. The device operates on regular AAA batteries and features an on/off switch so you can keep it from draining batteries when not in use. It also works on PCs.
