That's fair. It's obvious people like them. I don't get it. I don't understand how they use these phones and carry them around when they don't fit in virtually any pockets anymore, regardless of whatever benefits a larger screen offers. That's what the iPad is for. If I didn't have CarPlay and couldn't get a car with it, I'd probably look at putting an iPad mini in my car.
I had a 13 Pro for a couple months and eventually got so fed up with the cumbersome size and weight that I went back to my 13 mini. The mini never felt too small, even right after switching back. I miss the telephoto lens a lot, but it's still not worth carrying around that massive thing...constantly struggling to use it with one hand and getting it in and out of pockets or finding a place to stow it when not in use made it a real albatross.
But when the smallest current iPhone is larger than the largest iPhone from just 4 years ago, something is wrong. Like I said in another post, human hands have not increased in size that much over the past 4-5 years. It's clear that Apple is selling millions of these Pro Max phones, whether the size actually makes sense for mobile use or not. But as you say, everybody's needs and wants are different. It makes no sense that they aren't also selling a current device smaller than 6".
