Microsoft has announced its thinnest keyboard ever, the Bluetooth Mobile Keyboard 6000.

It is intended to cover the rising flood of netbooks that sport Bluetooth connections, but from complementary closely suffer uncomfortable keyboards.

Also available is a separate, portable keypad with their own pocket.

The keyboard measures only a few millimeters, “more than a AAA battery on the back and tapers to the front, making it easy to learn. How many of keyboards from Microsoft, the 6000 uses a Comfort Curve Design (six degrees, if you’re interested) for an ergonomic input experience with the straight keyboard layout of notebook computers compared.

“The teachings of the compact design, clean and really refined the conditions for the success of the keyboard,” said Chris Kujawski, industrial designer for Microsoft hardware. “There is nothing about the exterior design. We will remove everything that did not fit with the ideas and end up with something we’re really proud of – a compact, high-keyboard, which pairs perfectly with Bluetooth-enabled computer.”

IMS Research forecasts that shipped more than 55 percent of notebook PCs with Bluetooth until late 2010. No UK pricing has not yet been announced, but they will appear in the U.S. next month.
