I am sure some folks just won't want their gorgeous new iPhone 5 in a case, but based on the fact that the iPhone 5 (white or black) has an anodized aluminum back, they will be susceptible to denting. The previous iPhone models have had a glass back (much more dent resistant). There are numerous great cases to consider, with many already available. I use the Otterbox Defender which incased the phone inclusive of a front piece of plastic that protects the phone but works very well with the touch panel. There make thinner case that also afford dent and scratch protection and also more expensive cases that are also water-proof. I have the black iPhone 5 and my Granddaughter has the white. Both are fantastic looking, but we both quickly put them in a case. If you plan on carrying your iPhone 5 in a pocket you may want to avoid the cases made of material that would be hard to pull out of your pocket to answer a call.
