I found this original keyboard because it is possible to sureveler the front rather than the back part.
Indeed after having tried several days, it seems more natural, therefore, to have this positive position.
Some critics talk of a too rigid wrist rests. This did not bother me even though I guess it must be better.
The affected keys is pretty quiet and pleasant.
Many shortcut keys (may be too ..) Compatible with Windows 7 quite practical.
The mouse is correct, I would have preferred a rolled "not continue" (with jerk) of the central wheel.
Note that the following key / Previous are on both sides of the mouse which may seem unusual, but we adapt quickly.
