Microsoft has now announced its thinnest keyboard yet, the Bluetooth Mobile Keyboard 6000 and a Bluetooth Number Pad to complement it. Thinner than an AAA battery, the shiny new peripheral has a Comfort Curve design with a 6-degree curve providing an ergonomic typing experience.

"The design tenets of compact, clean and refined really set the stage 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."

The Bluetooth Mobile Keyboard 6000 and Bluetooth Number Pad are backed by a three-year warranty and are set to start selling next month for $90 and $45, respectively.
