The articles I've read say it is a complete fingerprint magnet, will scratch and have marks easily, looks like cheap plastic, is so shiny it attracts attention when often you want to use your phone somewhat inconspicuously, and if you put it in a clear case, it won't quite look the same through the plastic. I love the idea of a Piano Black iPhone, but it is not DLC like the Space Black Apple Watch and will get TORN UP! Even though it is metal it will likely look like plastic. And the fingerprints will be bad. The videos online from the event really show how nice the Black is and how smudgy and printed the Jet Black will get. I love the idea of the Jet Black but don't think it will wear well at all. I think there will be a lot of disappointment, returns or people casing it to protect it.
