ive never used a case on any of my devices(since g1 days, and every nexus since). i did buy a case for my n4. i put it on and immediately took it off. i hate how they feel in the hand, it really bugs me. naked is still the way to go for me. and ive dropped my phones many times, but this was the first time in all those years that my screen actually broke. what sucks is that it was all my fault. i had it in my lap(sitting on a bench at night), then stood up forgetting it was there. face down on the concrete it went. by now though, i forget that it did break. its in such a place that doesnt bug me, and the cracks arent visable with the screen on.
