Recently, Microsoft is readying a mouse that uses a blue LED rather than red lasers because the former can be used on a greater number of surfaces; this would mark the fourth great revolution in the way mice have evolved over the past few decades or so.

The blue LED will be used in conjunction with wide-angle lenses to replace balls, optical red and laser mice in one swoop.

The mouse itself is quite chubby but should fit in most hands, although it is a right handed device. Interestingly, rival company Logitech already has a Blue LED mouse on the market and there are countless DIY web pages on how to convert your red LED to a blue one.
