I mean, that’s probably what they would do t’were they to intro a “smaller” iPhone, but my hands still ain’t getting any bigger. In fact, I’d like this 12 mini to be about an inch shorter for easier one handed operation— my ideal iPhone would be the screen of an iPhone 6, 7, etc with the rounded corners and current design, but that ain’t happening. I hope they make something that’s not so crazy large though.
I agree with you on the current Mini size (12/13) being too tall.
I felt that way the first day I used it and my feeling about it (dislike) hasn't changed.
