As such, the shell is very good - the fit is excellent and the concept thought: even with the sheath can separate the tablet, wherein the top cover protects the tablet. Small magnets hold the cover closed while two snaps keep the "separation point" between keyboard and tablet together.
The flipside of the coin: the cover makes the tablet even thicker than it already is. So you walk quickly around with a leather-bound book that can be quickly bulky. And the thoughtful concept per se is used to - I have the Tablet again "the wrong way" opened, so I first looked at the keyboard instead of the screen. Especially in Netbookformat it makes the shell easily, keep them in the wrong direction and to feel the lid as disturbing.
But who able to deal with, for this envelope is a real recommendation.
