I think the slides in the keynote were actually on-point for this, there've been multiple innovations (multi-touch, high-DPI screens, Touch ID, their shift to in-house processors, computational photography), and it's really the aggregate that's lead to a great device. But break it down and it is an iterative, evolutionary process. That's why so many people often seem disappointed after every keynote!
That said, maybe the original iPhone really was a bit special :-)
It's just that the iPhone appeared all at once, whereas you have 5 keynotes to go from 2012's iPhone (the iPhone 4S) to the iPhone 7.
Since then we've got: 4G (LTE), Touch ID, dual-LED flash, NFC and Apple Pay, motion co-processor, 802.11ac, Lightning, Bluetooth 5.0, phase detection autofocus, 4K video and slo-mo 1080p, 3D Touch, haptic feedback, water resistance, wide color gamut, brightness increases, and several times faster CPUs and GPUs (allowing for far more demanding apps).
"a dramatic and wide-reaching change in the way something works or is organized or in people's ideas about it."
I didn't deny the actual definition of revolution and I recognized it. I am merely expressing my view on the following comments, which are what being discussed here.First comment:
Do you think phones are a "done" thing? I mean what we are seeing these days is more of an evolution than revolution.
It's always been an evolution.
Your comment: It wasn't always an evolution.
And for the first few years after that everything was changing so fast it was a revolution.
Breaking norm is a revolution, but the steps are evolution. Everything is evolution.
