I have a 14 Pro. I have no interest in upgrading right now. You get USB-C, the Camera button, action button and Apple Intelligence.
These features might be worth it to you, but I can’t see myself going through the trouble selling/trading in my 14 Pro just for a few upgrades. Using AI on my MacBook and iPad, I just don’t see it being worth it right now on my iPhone too. I considered the upgrade for USB-C as I was using my iPhone as my only computer for a while and experimenting with InfiniteX2P (an external display desktop interface for iPhone). But, my partner and I share a lot of lightning cables and accessories. USB-C would disrupt that a bit.
