Where were you in the years when Apple spun 3.5" as perfection... and then 4" as perfection? I recall almost no such comments about them when Apple endorsed them... when "one-handed use" was seemingly paramount and anything with a screen bigger than 4" was an "abomination." Funny how our opinions can so readily evolve to fit whatever a corporation has for sale at the moment.
I'm an NBA-sized man myself and I can see the merit of an SE-sized phone and right up to phablet-sizes. To each his own. One may readily agree or disagree with your opinion but there was a time when every iPhone fan readily laid their money down to buy the "perfection" of a 3.5" and then the "perfection" of a 4-inch iPhones- generation after generation- gushing, praising and defending the size to any and all challengers. If it was "perfection" for them then, it could still be perfection for them now... not getting lost in their pocket or purse then or now.
I had an iPhone 4 and 5. I hated how small the screens were. As soon as 6+ came out I was really excited. To this day I have no problem gripping or using my 8+ with my small hands.
