Microsoft has come up with a Notebook Mouse that does more than a singular function. It will also put on slide presentations up to a distance of 30 feet, and act as a laser pointer and media remote. With 2.4 GHz Bluetooth connectivity, it has 4-way scrolling, instant-view, 5 customizable buttons, and magnification capability.  At a size of 3.68 x 2.22-inches, it features an on/off switch to save some energy and a battery status LED. The multi-talented mouse is available for $79.95.
