Optical laser mice might have a rough time competing with the new Blue Track mouse from Microsoft scheduled to launch on September 9. In fact it’s already been spotted at the German Amazon.com store and at the YouGame online store . The Blue Track uses a blue (I’m sure you could have guessed!) LED and a wide angle lens, so that can be used on any surface. The Blue Track also has a USB wireless adapter so that you can connect easily connect it to a PC – very handy for use with a notebook - Gizmodo.
