Microsoft is expanding their hardware line up today, with the introduction of a new keyboard aimed specifically at mobile users. The wireless Bluetooth Mobile Keyboard 6000 is, as you might expect, a Bluetooth-only device that Microsoft has supposedly designed with comfort and portability in mind.
The device offers a much wider typing surface than a laptop's, but still manages to conserve valuable space with a detached keypad as well as extreme thinness. At its thickest point, the BMK 6000 is only slightly larger than a AAA battery.
For a price of around $100 you can pick up the keyboard, and the keypad runs an extra $45. For some, the additional functionality might be worth it -- especially if you travel a lot and don't like typical laptop keyboards. The advantage of it being Bluetooth removes the need for a wireless receiver or a USB cable chained to your laptop, another useful thing when on the road.
