I also have this case for my 11" M4. While I do like the protection and all of the different viewing angles it provides, I just do not like how heavy it is and I agree on the sharp edges. It takes away from the "naked device" experience. I had pretty much made up my mind to keep it but one thing that really bothers me is that that lining of the case around the front camera is not good. That part of the case is weak and it protrudes out showing the silver outline of the iPad. I most likely will return it just because of this.
