I made a post about this case just the other day:

Overall I think that the case is good in that it protects the iPad very well. Using the hinge is seriously awesome and fluid. It is really nice for switching between pencil, typing, and media viewing. It is not that great for reading. I prefer using the iPad in -portrait for reading and find that the bulk of the case prevents it from being comfortable and even a bit distracting.
Bulk is an issue as the case is rather thick. It doesn't feel that bad in normal use or carrying it, but using it with the front cover folded to the back, it is very distracting. It does add noticeable weight too. If you walk around using your iPad or hold it in your hands for reading, you may find it too heavy after a short period of time.
One other problem I have discovered is that in using the pencil, I have found myself rotating the iPad much like I would a piece of paper for drawing and I have found that to be cumbersome to some extent with this case.
The texture on the outside is certainly different as well. I am not sure how I feel about it. It has a very rough cloth, woven texture.
Overall, if your looking for a protective case and switch between typing a lot on the onscreen keyboard and media viewing or even drawing AND you aren't just using the iPad on your desktop, but rather everywhere (the couch, coffee shop, etc...), this case can be pretty good. Maybe a touch pricy at $79, but the unique selling feature of the hinge is almost worth it to improve overall a ergonomics and stability.
