The iPhone 7 looks rather impressive in Jet Black. However, given that it is exceedingly prone to scratches and smudges, it seems that using a case is necessary rather than optional. Covering the finish of a Jet Black iPhone with a regular case would be rather paradoxical, and I suspect that even a clear case would diminish or impair the look. Moreover, I do not understand the logic of Apple going through so much trouble to make anodized aluminum look like plastic. I have several devices with a piano black finish that are made of plastic --such as an Aukey power adapter, LG Bluetooth headphones, and a Seagate external drive-- and they need to be handled carefully. For all of the foregoing, I chose Black rather than Jet Black.
