Honestly asking, what would you consider innovation in a mature product line like the iPhone? It's 16 years old now. If you want bleeding edge technology in the iPhone are you willing to pay for it? Looking at a mature market like digital cameras, getting the latest tech like the global shutter in the Sony A1iii, you have to fork over $7k. That's 3x the average price of a full frame mirrorless.Being smart Alec are you? Apple was about innovation, then marketing, then money… where is innovation now? You call annual upgrade of each sensor (4 in total) innovation?
It seems crazy to expect the same leaps in tech that we saw in the first 4-5 generations of iPhones at this point in the product life. The MacBook saw massive leaps in tech the first decade it was around but has drastically slowed in "innovation" in the last 15 or more years. Small iterations add up to big changes over the course of many years now.
If anything, it's kinda nice being able to have a 3-4 year old phone and not feel left out bc the newest phones are only marginally better. My wallet certainly appreciates it.
