Microsoft unveiled its thinnest keyboard ever — the Bluetooth Mobile Keyboard 6000 — made exclusively for Bluetooth notebook and desktop computers. The Bluetooth Mobile Keyboard 6000 includes a stand-alone Bluetooth Number Pad that can be used with the keyboard or by itself.

Microsoft’s thinnest keyboard ever — just a few millimeters thicker than a AAA battery at the back — the Bluetooth Mobile Keyboard 6000 tapers down toward the front, so the keyboard is light and easy to pick up. And to enable the small footprint to still deliver ultimate comfort, the keyboard uses a Comfort Curve design for a more ergonomic typing experience over the straight keyboard layout of notebook computers. Microsoft’s Comfort Curve design encourages natural wrist posture with a slight 6-degree curve that is easy to use with virtually no learning curve. With more than 10 million Comfort Curve keyboards sold, it’s a consumer favorite, with 94 percent of users who own a Comfort Curve keyboard saying they would recommend it to friends and family.

The Bluetooth Mobile Keyboard 6000 and Bluetooth Number Pad will be available in October 2009 for an estimated retail price of $89.95 and $44.95 respectively.
