But that's because they want a phone that happens to be more expensive, not because they (necessarily) have a greater capacity to afford it than (all) those of us with cheaper ones, was my point.

Obviously there are people with a phone choice that has been limited by their ability to spend, I'm not denying that, I'm just saying you don't have to look nearly as far as billionaires for those who aren't.

If you prefer, I could equally have phrased it as people buying iPhones as frequently as they come out or not, either way needn't be billionaires; in the former case becoming a billionaire is unlikely to make you suddenly see that as an excess.
