Excellent keyboard. The keys give a nice response, and in the the 6 or more years I have owned this keyboard, I only broke one key during moving... So it is rather my fault.

The additional buttons (sleep, zoom +-, mute, ...) are well made, good placement.
The volume rocker is very nice! Works just as well as a capacitive screen from today. The touchpad is a little small, but as usually you have a mouse nearby this is not really a problem.

It has well enough battery. I never really think about it, just put it in its station once in a while...

The hardware finish is excellent, the gently slope for the wrists is well made. The keyboard is very thin so it is very comfortable to use.

Not to forget is the design of it, just beautiful!!!

The only bad thing I have to think of, is that it needs its own bluetooth dongle and cannot connect directly to the computers bluetooth...

All in all: excellent keyboard!
