The keyboard and mouse are products that haven’t seen much innovation over the years. Logitech however, has always been a pioneer. In 1991 they introduced the Cordless Mouseman and ever since, Logitech has been the leading source for wireless keyboards and mice. Unlike some infrared keyboards and mice, Logitech uses RF (radio frequency) technology which makes it unnecessary to “point” the mouse or keyboard at the receiver. Obviously, cordless peripherals allow for a lot more freedom and enjoyment of the computer. The Logitech Cordless Freedom Optical was the original wireless/optical combo from Logitech. Today we will be looking at a slightly modified version by the name of the Cordless Elite Duo.
