Just like its right handed brother, Logitech's precision laser tracking system, contoured thumb and pinky-finger grips and 10 navigational buttons, including e-mail and instant message notifications. The MX610 has a wireless range of up to 10 metres and also includes volume up, down and mute buttons for controlling music on the PC. The mouse is ready for release in early April , for a price of $59.99.
