Microsoft has added a new mouse to their Touch line. The Explorer Touch Mouse uses BlueTrack technology, combining the power of optical and precision of laser, for precise tracking on most any surface. There are five programmable buttons on this mouse, and the scrolling strip lets you navigate up/down or side-to-side with a flick of your finger. The wireless mouse comes with a nano receiver which is small enough that you can even pack your laptop in a bag with it still plugged in, or you can stow it safely inside the Explorer. The mouse will work with PCs or Macs, and it features an 18-month battery life. It comes in Black or Storm Gray (shown). The Explorer Touch Mouse will be available in September for $49.95.
