Unfortunately, some who have already purchased the new terminal iPhone 5 of those from Apple they achieved that the device scratches quite easily, at least on the aluminum case. In the image above you have a demonstration of this and some have been able to reproduce the results using the SIM card ejector, for example. All iPhones scratch regardless of the surface of their case, I don't think anyone can be surprised by this, so don't expect anything else.
Ditching the glass back and reducing the thickness of the glass panel on the front has affected the design of the metal band around the edge of the iPhone. It is now chamfered and while that looks pretty, we've already noticed that on the black model the edge has started to wear, revealing the shiny silver aluminum metal underneath the "slate" colored coating and, indeed, we've witnessed it on two separate models, ruling out a fluke manufacturing error.
