I also use the Android-Box (with keyboard / touchpad) I had tried them directly. This is possible without any problems, it comes completely welded on and can be tested extensively without it conveys an impression used in connection. Merely to load I had to make a small slit in the foil. ;)
Learning commands that are not pre-programmed, for example, turning on the box, was really easy. But I was really impressed by the gyro-mouse! Since I was able to train this kind of navigation is already on the Nintendo Wii, the handling was very intuitive.
I then tested the keyboard back in some form, the pressure point is okay for my taste. In a dimly lit room, the "FN / secondary assignments" to make on the keys, however, difficult to find. Nevertheless, in my view, not a real complaint.
The permanently installed battery was in the few hours that I've tested the keyboard does not get empty. Had me wondering.
Meanwhile, I play with the idea to create my Mele F10 Deluxe yourself, as my keyboard much bulkier and the touchpad is far from being so comfortable.
