Okay. Trying picking up a iPhone X (releases Sep 2017) vs iPhone 14 Pro and see the difference. There are a lot of quality of life improvements that make a noticeable difference in user experience.
- 120hz
- better battery life
- 2x as fast charge
- much brighter screen, always on if that interests you
- triple camera sensors, with wide lens vs double, no wide lens
- LiDAR to improve portrait photos
- faster Face ID (used 100s of times a day)
- satellite communication for emergencies
- MagSafe charging/docking ability
- 5G (really only find it useful for hotspots)
I can confidently say everyone of these features has improved my user experience. None of them by their self are earth shattering, but taken as a whole, the constant iterative improvements have amounted to quite a lot.
