Jordan Singer on Twitter posted this picture showing the iPhone with iPhoneOS 1.0 side by side with an iPhone 12 running iOS 14.0. The original iPhone home screen design was durable and endured the test of time. Some people will find it depressing to see so little changes but I do think it is a sign of an initial good design. iOS 14 brought the most significant upgrade, even more profound than the iOS 7 disaster.
