The Microsoft Bluetooth Mobile Keyboard 6000 is a battery-operated, wireless ergonomic keyboard featuring a curved design that encourages more natural wrist posture, while also reducing chances of an unwanted injury. The system relies on Bluetooth technology, which means that zero dongles/adapters are required — BUT, the PC used must have built-in Bluetooth for the keyboard to work with it. Included is a stand-alone, portable Bluetooth Number Pad that can be used with the keyboard or separately. Since the system does rely on battery power, a battery status indicator is included, as well as an on/off switch for preserving the battery while not in use.
