Black iPhone 5 Anodized Aluminum Back Scratch Test [Video]

Ever since the iPhone 5 went on sale a number of users of the black model have raised concerns over the durability of the device's anodised back. The folks at iFixit conducted their own set of tests on the black iPhone 5's anodised back panel, and the results aren't very encouraging. They also conducted the same tests on the iPhone 4S' glass back, which was much more resistant to scratches. Their testing actually involves a two year old trying to scratch the device's back with a bunch of keys and a metallic ring. Here's the video:
Although the scratching in the video is deliberate, it's a pretty good representation of the daily wear and tear your iPhone might undergo.
