Yesterday, Logitech unveiled it's wireless MX Air dubbed the "Air Mouse". It's a sleek rechargeable laser mouse that, when you pick it up turns off the laser sensor and uses the dual embedded MEMs gyroscopes inside it to detect angular motion in the air, as well as an accelerometer, so the mouse knows which way is up. Nothing news if you are a Nintendo Wii gamer!

"All the motion computation is done in the mouse... You just have to plug the Air Mouse to your notebook or desktop system to start using it... There's no setup required", said a Logitech product manager.

A touch sensitive scroll-panel replaces the traditional scroll wheel

The Air Mouse does not have a scroll wheel. Instead, the MX Air uses a touch-sensitive "scroll panel" for super fast scrolling with the touch of a finger. A swipe of the finger across the surface enables the inertial scrolling mechanism, which adjusts its speed according to the speed of the finger swipe.

Logitech's MX Air cost about $150, more than twice the price of Gyration's GO 2.4 Optical Air Mouse.

"Gyration's air mouse uses a mechanical gyroscope and is not as responsive as ours", insisted the Logitech rep.
