good material, very comfortable

Me trying - unsuccessfully - to find a keyboard that is really nice to use, well I'm finally satisfied!
1) the keys are very soft, and make almost no noise. Only small problem, the keys are calibrated slightly differently compared to my old keyboard, suddenly, my fingers often get out of hand ... but this is just the time for a rehab!
2) put in more than easy road !! ("Plug and play")
3) easily configurable, the keyboard has useful shortcut keys which I already use it and already very often.
4) the keyboard is not afraid of liquids (coffee style ....), which suits me well, given consumer I make.
5) Battery consumption - which I can not tell you more - that would be very tasty (I will talk to you in a year)!

For the mouse, it's pretty good, but I am a bit taken aback by the keys on the side, on which I happen to inadvertently support ... Otherwise, it's a laser mouse, which has still nothing to do with respect to my optical mouse! The accuracy is enhanced, which is useful when working on photos.

Only downside ... I'm not a priori pro "wireless" for health issues. Why do they not offer as good keyboards WITH thread?

Updated June 2012 (ie 22 months after acquisition): mouse problems that no longer works well AT ALL, the semblance beam answer discontinuously ... and it's not a battery concern since I have changed 2 time to check. So this does not seem to be very durable over time.
As for the keyboard, no major concern, except that the most commonly used letters (E, S, N ....) are already beginning to fade.
