Do some shopping around & be sure it's exactly what you want. There are a lot of case options. I personally wouldn't be able to stand that one, due to it covering part of the face/bezel of the device.
This is me as well.
I had a similar case on my Thrive and seemed to be forever hitting the edge when swiping.
I have a BluRex on my N7 that doesn't obstruct the screen, but the magnet feature works properly only about 50% of the time.
It almost always wakes it up, not so much putting it to sleep.
Other than that it's great.
Edit: Just noticed another bonus for the BluRex case...
When (if) the dock becomes available, the case won't have to be removed to put the N7 into the dock.
Just pop the 2 lower clips and the pogo plugs are fully exposed.
