I run the keyboard on a Zotac ZBOX AD02 Barebone Mini computer with the Linux operating system Ubuntu 12:04. Amazingly, the keyboard worked (and the touchpad) after plugging the mini USB receiver right away without further assistance with Ubuntu. The sensitivity of the keyboard and the touchpad are very good. The mouse pointer can be precisely positioned. The function keys can be customized with Ubuntu easily remap as desired. Scrolling with two and emulates the right mouse button with three fingers on the touchpad.
The mini-PC is connected with me with the flat screen TV. Therefore I use from the keyboard of the couch and sit normally 2.5 to 3 meters away from the receiver. I have tested a distance of 6 meters positive. However, there are no objects between the keyboard and receiver should be located. Disconnections as in other Rezesionen I can not understand. For such problems, you should relocate the receiver possibly with a small USB extension forward but initially.
I am very satisfied and would recommend the keyboard.
(The smaller version (E2700?) Might still be handy on the couch.)
