I have the keyboard for 3 weeks in operation, mainly under Windows (with additional Bluetooth receiver). Optimal is the switch to iPads and iPhones with a single keystroke. The writing feeling is also prima after a short. Well well, that should be able to make the keyboard mechanically.
Unusual is naturally invoking special functions with AltGr or Windows key. The time has prevented the use of the Apple keyboard with Windows.
Anyone looking for a wireless keyboard for use on Win / Mac / iOS, nothing gets better.
