Did you know that optical is different from laser?  Anyways, Logitech is looking to pair up their laser mouse with a keyboard for a cordless mouse-keyboard bundle.  The relatively new laser tracking technology is the result of an alliance between Logitech, the world’s No. 1 manufacturer of mice, and Agilent Technologies, the leader in mouse tracking technology. The nearly singular wavelength of a laser’s light is capable of revealing much greater surface detail than the red LED found in optical mice, in fact 20 times more detail. As a result, the laser can track reliably even on tricky polished or wood-grain surfaces.  The mouse and keyboard package will be available in Europe around March, and here in the US by April, retailing for $149.
