Switch and satisfactory range!

A keyboard with a switch to not wear out the batteries and store the keyboard behind the sofa cushion when not using it (and always have at hand)? Excellent!

And integrating the multitouch touch pad Win8! Indispensable!

Only downside, you have to have the Logitech Setpoint drivers for a good pointer acceleration and multi-touch gestures are active (and I'm not a fan of the drivers who have a soft open in the systray)

In any case it's still much better than getting up every time!
