I don’t quite agree with that.As iPhones become better and better over the years, small steps eventually bring tip-over points, when technology starts to enable things that we couldn’t imagine years before. These developments enable not mere steps, but leaps forward: the iPhone X’s all-screen form factor and Face ID; iPhone 7’s Portrait mode; last year’s Dynamic Island and 48 megapixel main camera.So here’s iPhone 15 Pro Max. This year brings a leap in materials and silicon, but marks an evolutionary photography step. Or does it?
