It’s pretty well established that this is a plateaued product. What groundbreaking refinement do you expect? Still, it has a way better screen, pro motion on top, Face ID, action button, more screen real estate, dramatically more ram and overall performance, a way better camera system, speakers, etc. Does it reinvent the wheel? No, and it doesn’t have to. But discarding 6-8 generations is pretty wild by today’s standards. Cara still have four wheels also and no one goes out pretending that the form factor needs to change.
