An ideal mouse Windows 8!

The new Windows has something confusing at first ...
It is quickly lost with the tile system, the office is considered an application ... and juggle all this is rather painful at first, especially in anticipation of the Windows button in version 8.1 ...

And now so arrives the new Microsoft mouse ... With its touch dedicated button to switch between Windows 8 apps, apps and between offices ... Really well thought out and ergonomic, the grip is very fast.
Bluetooth seems well managed, no dice stall, no conflict with other Bluetooth devices operating in the same time ... Very reactive, it has it all.

The only downside for me is the top glossy (I would have preferred a matte surface like on the bottom of the mouse).
The other downside for left is that it is thought that for righties, ergonomics for left must be much less appropriate, not least by the profiling of the beast ...

And my reserve will be on autonomy because I have not enough experience to judge. I read on some forums that it could take US 10 months for normal use. I doubt it but if it is true, it will be almost perfect!
Editing the comment January 12, 2014: A few months later, I still have not changed the batteries. Autonomy will perhaps not 10 months but it is in any case already now excellent!
