As I stated before, people are going to get what they want. And if it scratches anywhere near as much as the 3gs or 4, trust me, some folks will be angry...EVEN IF you put in a case. Why? Because it will probably be scratched right out of the box. That's not "aging"...that doesn't make the phone have more character.
I don't recall seeing too many angry iPhone 3GS or 4 owners on this forum.
