Excerpt: The Gyration Air Music Remote is absolutely awesome when it comes to controlling the cursor of a home-theater PC. But this device doesn’t deliver on its bigger promise to be a high-end universal remote control. Like all Gyration remotes, this one uses a gyroscope to determine its own position in three-dimensional space. With its position established, the remote translates those coordinates to move a mouse cursor on the two-dimensional plane of a computer screen.
Pros: Absolutely fabulous device for controlling a cursor from your couch.
Cons: Expensive. Monochromatic display is too small and is limited to iTunes and Windows Media Player.
