Logitech MX Air Review at CNET
CNET have published a review of the Logitech MX Air gyroscopic mouse. 'There are a lot of reasons why you may want to move your mousing out of the standard 2D, flat-on-the-desk mode. For computer users with persistent hand and arm pain caused by poor ergonomics or repetitive motion (sometimes called mouse arm), gyroscopic mice like those in the Gyration line have been good solutions, letting users lift the mouse up off the table and control the cursor by moving the mouse through the air. Later on, home theater enthusiasts also discovered gyroscopic mice, and these devices have become a popular, if not exactly common, choice for controlling the functions of a Media Center PC from the living room couch.'
