There’s a little disclaimer at the bottom of the iPhone 7 tech specs page that makes me sad:
The high-gloss finish of the jet black iPhone 7 is achieved through a precision nine-step anodization and polishing process. Its surface is equally as hard as other anodized Apple products; however, its high shine may show fine micro-abrasions with use. If you are concerned about this, we suggest you use one of the many cases available to protect your iPhone.
I really like the look of the jet black in photos, but between this note and photos of the matte black option, I’m going matte.
