I had a couple of Max models but went back down to regular size because it was too big. However, Mini is just too small for me to handle well any more. I make too many mistakes on the smaller on-screen keyboard, and forget reading on it without putting on my glasses first.

I could't care less what size other people use, and I use social media maybe half an hour a day, if that. The regular sized iPhones are the happy size for my older eyes and thumbs.
