Enthusiastic for ergonomics, disappointed for features

Here together with a keyboard / mouse / digital pad called "ergonomic" (supplied with batteries) which is really excellent from that point of view.
Comfort is real. The position of the wrists, whose support is very soft, is perfect. The buttons are really nice to hit and also very quiet. And the amazing thing is that the right hand position - using the standpipe under the keyboard - promotes good position back. Since I have this keyboard, I'm standing much straighter in my chair!
As for the mouse, same feeling: it helps to have a position much more natural hand. I already feel the benefits.
Well, this new material still requires some time to adapt, because at the beginning we seek many keys, even if good habits in terms of typing. But you get used quickly. For me it's been 3 days since I have this keyboard and I write again without looking at my hands. That said, the remark of one of my colleagues is relevant: if you work on multiple computers, thus with different keyboards, it is not obvious at all to switch from one to another.
Another problem: I'm not a fan of the separation of the digital pad. I find it infinitely more practical in its usual place, ie right of the keyboard ... otherwise, I spend my time looking at having to move the arm and thus change position to achieve it. So less precisely the ergonomic level.
Anyway, overall, ergonomics, I give 5 stars to this set keyboard / mouse without hesitation. I warmly recommend to people doing a lot of typing and suffering including pain in the hands (by dint of always doing the same things).

By cons, features side ... I think this set keyboard / mouse could have done better, especially considering the price where it is sold.
First, it is only of interest if you have Windows 8, because some keys are specially assigned to "quirks" of this operating system, such as screen sharing (which I use not really), the to / from the classic Windows screen and screen applications ... In short, as Windows 8 is not a panacea in terms of ergonomics precisely, so you distinguish the contradiction.

Other features are not of much use to me, especially as the "share" of which I have not yet understood the operation, since I can not share web content from Firefox. But if I understand correctly, W8 forces us to connect through applications (Facebook, Twitter ...) and therefore through the Microsoft account, supposedly to facilitate sharing ... as I find it rather contentious for privacy I refuse these interconnections.
It is the same for the shortcut "windows" on the mouse, which I do not really see the point, since it is exactly the same as on the keyboard, but ...
There has against more attractive buttons with direct access to the "Device" and "Settings".

Some classic shortcuts - and quite useful yet - were "failed" or I especially liked my old keyboard to 3 francs 6 under:
- A small button to turn off or put it to sleep, it was too much ??? where ease of use? Honestly! With W8 it takes 3 clicks to turn off the computer!
- When I was listening to music I could forward / backward between songs, here it is no longer possible (only play / pause)
However, to compensate for the shortcomings, it is still possible to assign custom functions to a few keys "customizables."

Finally, I deplore the absence of a TRUE manual on the keyboard. This is because the delivered documentation is unnecessary and cumbersome because it is translated into many languages. there are no details on the features and possibilities offered by this material. I tried to find a more elaborate documentation on Microsoft's website ... no better. So again, can do better.

Here, the copy is to review the side of keyboard shortcuts, and it's a shame, that's why I noted only 4 stars. But I will remember all the same that it is a real success in terms of ergonomics, and this product is worth it.
Well, I have not come full circle ... but if I see something interesting, I will certainly put this comment to date.

PS.Gauchers refrain, the mouse is made for right-handed

UPDATE 24/11/2013: Another star less because to use this keyboard is not always a "gift". Regularly, I tear my hair because it is sometimes impossible to type anything, the result on the screen is dramatic: he zaps me a letter two !! as if reception was not! So I find myself typing "speed" beginner, 1 finger to be sure that each key registers well. It really is extremely annoying.

Updated December 14, 2013: I am writing now with a wired keyboard has all that simple. In fact, I ended up giving up scuplt use the keyboard because I was going to end up tearing my hair because of this one. It's simple: he walked half the time. The ordeal. I think there was a serious malfunction in the transmission / reception of the waves. Short. I would be curious to have other feedback, so whether it is only mine posing these problems.
NB. I already had wireless keyboards that do not ask me such problems.
