"Logitech has been developing and manufacturing computer peripherals since 1981; starting with computer mice, Logitech has expanded and has become one of the markets leaders in peripherals. One of Logitech's newest innovations is the Cordless Desktop Wave Pro. Designed for comfort and functionality, the Wave Pro forms to the hands without the need to adjust typing style. The wave shape contour of the keyboard naturally fits the curvature of the hands, while the mouse is ergonomically fitted to the hand as well. The MX-1100 mouse (included) sells for $79.99 on its own and has adjustable (up to 1600 dpi) dpi resolution. Logitech has stated that the keyboard battery lasts up to 3 years (not tested by hardware-pacers) making this the longest lasting battery for a keyboard that the Hardware Pacers staff has seen."
