Microsoft today unveiled what it claims is its thinnest keyboard ever, the Bluetooth Mobile Keyboard 6000. As the name suggests, the new plank is aimed exclusively at Bluetooth notebooks and desktop PCs, with Bluetooth-enabled notebooks projected to account for more than 55 percent of all laptops by the end of 2010, Microsoft says.

"The design tenets of compact, clean, and refined really set the state for the success of the keyboard," said Chris Kujawski, industrial designer for Microsoft Hardware. "There is nothing extraneous about the design. We removed everything that didn't fit with those ideas and ended up with something we're really proud of -- a compact, sophisticated keyboard that pairs perfectly with Bluetooth computers."

Measuring "just a few millimeters thicker than a AAA battery at the back," the Bluetooth 6000 sports an ergonomic design with a 6-degree curve, a design Microsoft says is preferred by 94 percent of users who have ever owned a Comfort Curve keyboard.

The Bluetooth plank will be available in October for $90. There will also be a separate Bluetooth Number Pad, which is also be available next month, and priced at $45.
