Microsoft has launched a wireless keyboard integrating a remote control, keyboard and mouse pointer. The all-in-one keyboard allows users to send instant messages, watch movies, view images and control a TV. They keys have backlit, designed to make the keyboard easier to use in the dark. Keyboard buttons dominate the middle portion of the device, while mouse functions are located on raised panels on the left and right sides of the unit. The remote control buttons, also on the raised panels, can be used to change channels, raise or lower the volume, or control a DVD movie, among other functions. The keyboard uses 4 AA batteries and utilizes an infrared wireless link to the PC and can operate up to 30 feet away from the system.
