I had the official keyboard of Apple in front of this keyboard. This was not explicitly designed for the new iPad, which is why some features were not available. Thus the device could not be locked and unlocked using the keyboard again z. B.. The Logitech keyboard provides for a key, what comfort is significantly better because you do not have access only to the iPad for / SperrenEntsperren. Also, the idea with the shell, which can be converted quickly and easily into a small stand, super.
The only drawback in comparison to the Apple Keyboard: Function keys for setting the screen brightness missing. But since you do not constantly adjusts the brightness, I prefer rather have a lock / unlock key.
All in all, a great product with a great typing experience and many useful features.
