And that's fine, but at the same time don't lump everyone into the same category. There are some of us who find certain features to be things we really want and are willing to pay for.
For example, I had a similar conversation with someone when the Always On Display came out with the the 14 and they were mocking everyone who considered upgrading. That has been such a wonderful feature for me, which which I'd been waiting so long. Similarly there are folks who will see something in the 16 that they really want, and they'll upgrade from a 15.
Or, people in multi-phone households like mine are different too - when I get a new phone, my wife gets my old one, our oldest gets hers, and my poor daughter gets my son's (luckily everyone really looks after their things well!!) So again, we tend to upgrade nearly annually and I'm the one who most loves gadgets, so I get to enjoy a new phone.
I wish everyone would just worry about themselves, their own needs and wants, and stop opining on everyone else's decisions.
