Microsoft has just announced the Explorer Touch Mouse, the newest addition to Microsoft's growing wireless touch-enabled mice line. The Explorer Touch Mouse features a touch strip with both vertical and horizontal navigation as well as touch scrolling. Other features like 5 customizable buttons, BlueTrack blue laser sensor for tracking on virtually any surface and an impressive 18-month battery life are all packed into the sleekest, ambidextrous body a mouse has ever seen. The good news is that the Explorer Touch Mouse is both PC and Mac compatible - even OS X Lion. The bad news is that it isn't Bluetooth enabled, rather RF dongle enabled. It will be available in September for $49.95 in black and blue.
