Logitech wireless keyboard MK220, Raspberry Pi

This is a nice wireless keyboard.

For XMBC i will recommend more joystick style keyboard, but for other operating systems and tasks the Logitech MK220 is just brilliant.

Keyboards need two AAA 1.5 V batteries which goes at the left side so the center of gravity will go on the left :D Mouse you can satisfy with bigger batteries than keyboard. Mouse will eat two AA 1.5 V batteries.

There are no power off switch on mouse and keyboard, but Logitech will promise 5 months to work without battery change.

I think the mouse pointer reaction is very good.
