I use the keyboard for now good 2 weeks and am more than satisfied. It is through the large keys take some getting used to, but you get used to very quickly. At first I thought she swallowed letter, this is not so, you have to press a little harder the keys simply. As fragile as it seems it is not fact. The stop is super quiet, I hear, however, always only my colleagues, with its ancient IBM keyboard to me :)
The few extra buttons I use, because there have found place my important programs. Eclipse (on the calculator button), Winamp, Firefox and Thunderbird. A pity, I find that you can not remap the most unnecessary button (Standby). This shortcoming is, however, worth no penalty to me.
