I got an Otterbox for our first iPad (v1). It seemed to offer a lot of protection, but it was big and heavy and expensive. The idea of using something like that on a phone seemed counterproductive (it would make it harder to put in a pocket, for one thing).
I've got our Nexus 4 in a thin generic leather flip-cover like this (but not this exact item) - http://www.amazon.co...us/dp/B000LGAF0I/ . It's Ok, but not ideal.
I've thought about what I would use if I got a Nexus 7 or iPad Mini or similar and hadn't found something that I was happy with. The Cruzerlite TPU case looks like it might be a good compromise. http://www.amazon.co...el/dp/B00EDNK64A/
Thanks for mentioning it!
Cheers,
Scott.
