I'm about to buy a new iPhone 7. I want the Jet Black because it has much better grip than the others, and I never use a case (only a Sena Heritage Slim pouch). Since I upgrade every year, I always sell my old ones on eBay. And since I take good care of them, they basically look brand new, and I get a good price. However, I'm now worrying that after a year, the apparently scratch prone Jet Black iPhone may look so beaten up that I won't get much for it when selling it. For you Jet Black owners out there, do you think a careful person will be able to use one for a year and still have it look almost new after that? Also, if someone is using a Sena Heritage Slim pouch with their Jet Black iPjhone 7, does the pouch in general or specifically the seams inside scratch the finish?
