The other day I stumbled across this Microsoft Keyboard. Although I am anything but a Microsoft fan, I am quite convinced of the Tatstur. The device is compact and makes an extremely sophisticated look. The solution to the lid as (also magnetically held, removable) Holder is good, though abgeguckt at Apple. The keyboard turns off when you open and when closing: Discreet, well-designed and chic. iPhone and iPad are very stable in the holder and it can work well with it. For a keyboard of this size, the part of the typed excellent. The key layout is normal, only the cursor keys require some getting used to: The cursor up and down arrow keys share space a normal key, but what is initially irritating. The Sondertatsten for volume etc. work as expected. The rechargeable via USB Battery lasts forever, but that's in almost all devices of this kind that.
Conclusion: Certainly not cheap, but the price of quality seems quite appropriate and is likely if I judge that right be amortized over the long period of use entirely.
