Initially I did smile thinking of having the chance to write with my MBP keyboard on my iOS devices … not anymore.
The installation and setup is really simple and without any hiccups. I have started to appreciate the fact that I can write a lot faster now. Especially, while using applications, which do not have a counterpart on the Mac, e.g. Drafts etc. — this is the only reason I did by 1Keyboard, which avoids having to purchase an additional Bluetooth keyboard, nice!
The only little annoyance I have experienced is the fact, that while using the U.S. keyboard as the input source, special characters are not always transferred correctly — e.g. the "ß" in German is translated to ".", the Umlaute are recognised though.
Definitely worth the money!
