It seems like the people who say the "new" one is thinner, lighter, more elegant, etc, all have cases on their phones. So in essence, the case sets your phone back a generation or two.
I never understand why people use cases. What's the point in preserving something in mint condition if you never see it without the case?
I could care less if my phone gets dinged, or scratched a bit, but complete failure is an expensive fix.
