I went from a 5S (first phone) to a X, to a 12 mini. The “standard” size still feels like the outlier to me. However, my eyes aren’t getting any better, and some apps don’t bother to scale as well on a mini, so I don’t think I’ll mind ending up with a slightly larger phone in the future. I want to wait until the non-pro iPhone lineup gets the ability to take “spacial video” first, though. I think that’s a feature I’d make frequent use of.
