Logitech unveiled its MX Air Mouse this morning, a laser mouse that works on the desk and in the air. A somewhat similar product from Gyration has been available for a while. However, the underlying technology isn't quite the same. The Air MX uses Freespace motion control technology, which interprets how you move the mouse regardless of where you point it ensuring accurate and responsive navigation at a range of up to 30 feet. That alone sets it apart from Gyration's device which needs to be pointed directly at the computer.
