So you know, I thought it was a keyboard where I should still shake my fingers to type three letters to each key, the battery should be recharged often and well I was wrong all along the line. This keyboard is very comfortable, the keys are curved so no errors. There are lots of features (multimedia, touch windows, ctrl + alt + del) useful. The touch-pad is responsive, precise mouse clicks, a pad with four arrow keys .... Anyway all this coupled with a battery that fits easily three weeks in normal mode (3 hours per day) dongle stored in the keyboard and recognized by any machine without having to press a button ... happiness.
For me, a raspberry, a 120000mAh PowerTank, this keyboard and I move with self pc in my pockets. Ok I have not yet found a solution to the screen without using a pico projector (not at the point in my opinion). But it will come ;-)
