I have long agitated for a 5 style phone (Black/Slate) in the Pro Max size. It'll never happen, but it'd be nice.It is impossible to make everyone happy. I still think the iPhone 5/5s was the highpoint of phone design. If a new iPhone generation came out paying homage to the 5/5s, at least slightly smaller than the base 14/15, no camera bump, flat sides, enough bezel at the top and bottom to hold the phone without touching the screen, I'd be queuing up for one on release day, especially if it were thick enough to have better battery life! Clearly that's not going to happen because that's not the way design is going.
By the time I'm ready for a new phone, they'll have an entirely new design, that'll probably be quite nice, and I'll be happy enough with it. I just hope the 'MAKE IT BIGGER AND THINNER' push is over by then, people who want their iPhones and iPad minis folded in half have them, and phones are trending smaller again. I loved going down in overall size from the 8 Plus to the 14, and hopefully my next phone can be slightly smaller again. I don't think I want to go all the way back down to a 5, in size, but no bigger than a 14!
Sorry for the incoherent rambling. I just got up and haven't had my coffee yet.
But you're right, it's impossible to make everyone happy because my ideal size for a phone is somewhere between the size of the Pro Max and the iPad Mini. And that's never going to happen either.
