iOS: A visual history by The Verge
A very complete visual history of iOS by Dieter Bohn and Aaron Souppouris. It’s a trip down memory lane.
I like how they added important changes to all the iOS versions ever released. It just shows how Apple likes to improve, slowly but steadily.
As Dieter and Aaron put it:
The progression of iOS has been a steady drumbeat of new features that often felt inevitable. Apps, multitasking, and even cut, copy, and paste all seemed to have come late to the game compared to the competition, but in each case Apple took its time to ensure that the solution it offered matched its own high standards and was designed for future growth.
