This is now changing with the Bluetooth keyboard. About Bluetooth can connect a five devices and additionally another via USB. Thus, you can still change after logging in easily between devices. This works well with Android devices, iOS can not I unfortunately test.
I feel the letter on the keyboard quite pleasant. The keys are quite flat and have a pleasant pressure point. Only with the spacebar I have my problems.
The special keys "Volume +/-" and "Mute" functioned under Windows only, if the mixer was opened, worked on Android at least "noisy / quiet" always, "Mute" no. Start the computer worked under both systems. From the accessible via the FN key functions, not folded on the PC, but mainly with Android.
Switching on each device works very simply: FN + F1 ... F6. Which device is being actively driven, is indicated by a blue LED. To connect a port is selected and then FN + "+" from the keypad and you can already activate the Bluetooth search on the device and select the keyboard. Thanks rubberised feet do not slip on the desk as well.
Conclusion:
The keyboard leaves me with a good impression and I use se like a keyboard replacement on the notebook.
