This keyboard is pleasant to touch and offers a good position for the hands. The best: full of buttons for launching reading mail, web access etc. (an application scores are available and 5 are programmable very simply; it also has profiles already programmed) without going through the menus or icons. The least: suddenly we no longer has access to the function keys, use the rocker button between the function keys and a set of 12 applications. The two zoom buttons (+ and -) may not work with all computers or with any software application. The balance sheet still remains very positive.
