It's rumored that Microsoft is going to release a Sidewinder keyboard, one of the special things about this board is that it will have a detachable numeric keyboard that can be attached to either side of the Sidewinder keyboard.
It also appears to have some programmable keys on the left-hand side. What appears to be a range of multimedia keys can be found at the top of the keyboard, although we're not sure what the two round things are meant to be for.
The site says the Microsoft Sidewinder keyboard will be launched in September for $79.95 (50EUR).
