Probably gonna jinx myself here, but I don't have a case for mine and I haven't dropped mine yet. I do use the case that came with the phone whenever I'm out an about though. I just keep it in my jacket pocket and not on my belt.
I can understand why some people want to protect this puppy since it cost so much and seems so fragile. I just hope to be extremely careful and not drop it.
I don't have insurance on the phone so I hope that doesn't come back to bite me later.
But I hate having a case on my phone. Even the clear one. It's fine for a little while, but personally I just like using it without any protection.. Sorta like...nevermind, bad analogy
