Microsoft is preparing the Mobile Memory Mouse 8000, a laptop mouse which combines several important features. Above all is 1GB of internal memory, allowing owners to treat the 8000 as a USB flash drive. The mouse also offers not one but two wireless options: Bluetooth or 2.4GHz, the latter through the same USB port that allows file transfer. A switch flips between the two. The USB connector further offers magnetic charging through a direct connection.

The sensor is a high-resolution laser, and added controls on the mouse include a tiltwheel and two side buttons, assigned by default to "Magnifier" and "Back." Being a Microsoft mouse, the 8000 is immediately compatible with Windows Vista's Flip3D interface. It should be released in October for $99.
