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 opened up the case and there's not a scratch on it. Aside from some dust the phone is still in mint condition. The case is nearly perfect too aside from one tiny bent plastic part under the rubber shell.
I won't say which case it is because I don't want to sound like an advertisement, but IMHO it's totally worth it to get a good one.
