I just put my iphone 5 in an otterbox defender. Despite the litany of complaints about it's size and bulk, I wanted to play it safe my first time 'round and was hoping that the size/weight criticisms were a bit exaggerated. They are not. It is very bulky in a jeans pocket, or regardless of where you carry it. I want excellent protection but the defender case is a bit too much case for my needs. What about the commuter? The phone touches rubber not plastic and the entire case seems considerably slimmer. Which one do you prefer?
