There are some Poetic cases (coming out later this month). They're on Amazon for 1 cent US (with 4.95 shipping). I have a case for my 2013 Nexus 7, it's pretty nice actually!

There's also some Caseology cases for the N5 - which seem to be well reviewed for their N4 cases.

There's also one from Supcase that looks pretty nice too...

I thought I was set on the Spigen NeoHybrid - but the redditor who posted some pics of it breaking super easy on the galaxy s4 make me really sad (because it looks very very premium, but appears to be sadly cheap for wear).

I'm really struggling here. :( So hard to choose something to protect it!
