All bumpers and cases are a crime, and detracts away from the beauty of Apple's products. Why buy something so nice looking, only to go ahead and cover it up and hide it from the world? It's like marrying a hot model and then forcing her to wear a burka 24-7-365.
People who put bumpers on their phones and people who use cases permanently on their Apple devices reminds me of strange people who keep plastic covers on their sofas at home. I could see using a heavy duty case for an iPhone if I were a soldier serving in Afghanistan or something, but no way should any civilian ever cover up any Apple products with ugly bumpers and cases. It's only a phone, and if it breaks, then either get it repaired or go and get a new one. Or just don't be careless to begin with, and the chances of a phone being damaged is greatly decreased. Do these people also walk around with bicycle helmets on their heads 24-7? Maybe they should.
