This keyboard works well with Ubuntu 12.04. The distance to the key of the keyboard is a maximum of 4m. The keyboard is a little but not too much plastic, the keys are comfortable to type. The touchpad is accurate and easy to use, drag & drop for the key click is not very easy to use together with the touchpad, you have to juggle. When the keyboard is on the knees, we must keep to the end of the lap, otherwise the connection is wrong with the key. -1 Because of the error, I got a Qwerty keyboard German, yet the QWERTY keyboard is declared on the site, it must be verified.
