I love the look of the IP4 naked. However due to my past experience with otterbox cases I do agree they add bulk but they protect the phone to it's fullest. Some people might not need such protection but I work all day in the street and need the most protection I can get. With that being said, how many are waiting for the release of the otterbox defender series?
