iPhone 5: a case-free phone
After using the iPhone 5 for several weeks, I can say that it does not need a case to be safe and durable, other than accidents like dropping the phone. But that's the problem for any device.
Its solid construction with full glass on the front and almost full aluminum with plastic bands on the back make it scratch free.
In one world, very satisfied.
I am posting this as that was a concern I had before. Some potential buyers might still wonder. I wanted to keep the phone slim and light. I think this is the most durable iPhone.
