Yes I also wouldnt want a thinner phone, because then it would just be too thin. Even now I love my bumper case so I can grip it just a bit easier. Although it will need a battery replacement next year... Starting to need a bit too much charging during the day ( a couple of 20 - 50% top offs) .
But loved both (?) minis. I hope mine lasts a long time. Maybe the new SE will be a similar size or Apple comes out with a durable foldable.
I predict, though the Plus phones won't ever have the same level of a cult like following of mini due to larger phones being prevalent everywhere (platform agnostically speaking), and Plus effectively replacing mini line and people always being bitter about that (but it's Apple you should be upset with , not the replaced product line IMO which you can opt out of buying) and Pro Max phones very much continuing to be a thing that is 'close enough' for most people or people who are non-Pro non-starters, no exceptions but...
that when iPhone 17 'Air (Plus replacement)' arrives, and the honeymoon novelty phase wears off people will be clamoring for a Plus equivalent return:
two cameras,
sensibly thicker body to accommodate battery life while still being pretty light overall (same weight as iPhone 16 Pro)
maybe more fun colors or something retrospectively since the regular colors are more fun than years past overall, even with some contention there
and 60hz which while its not as ideal visually as 120 has its battery life benefits
when the razor thin, single camera, Apple prototype-y cell modem, with razor thin battery life pumping out 120 drops.
I'm positive there will be some 1st gen MacBook Air or 1st gen 12-inch MacBook level concessions to factor in to getting shiny new thing that is supposed to pump some new enthusiasm into iPhone releases.
