Microsoft is preparing a new Ultimate Keyboard for Windows Vista:
The new Bluetooth-based wireless keyboard is aimed at making your Windows Vista experience even more pleasurable with such features as a backlit keyboard with ambient light sensor and proximity sensing to power down the lighting when you leave the room. Even more impressive is the included pad that charges your mouse when not in use. It's probably using some kind of induction charging system similar to what's used in A4Tech's BatteryFree Mouse. The ergonomic keyboard also features a host of media buttons and controls to take advantage of Vista's multimedia capabilities and has a 30 foot range. But for all its features, the new keyboard ditches the traditional numpad that most have grown accustomed to.
It will be launched close to the launch of Windows Vista. More details and a photo over here.
