So here's an unrelated question:

I want a case for my Nexus 7. I've poked around on Amazon and MoKo makes several popular cases (leather-wrapped, clip-on, and rotating). These seem to include a magnet to trigger the auto-wake-up feature of the tablet. One friend of mine loves his hardback book cover-style case. I'm sure there are many more variations.

I'm not entirely sure what features make for a good or bad case, although the idea of having a hand-strap on the back to make it easier to hold sounds attractive. Thoughts?
