FWIW, I don't like cases either. I have very high standards. But got to say... just bought the Spigen slim armor S case. It's not bad. Nicest looking and best quality case I've seen yet. Slim design. Good build quality. Don't know how long it will last but maybe buy it and try it. I have a feeling it's about as good as a case can get.
