Most people use their phone for far more than SMS and "phoning" these days. You are an anomaly these days. That's neither good nor bad, it just is.
Other than a few lucky ones, we aren't big fans of contracts, replacing phones every two years, we enjoy our pre-paid variants, and only replacing them when it actually is required.
Even when we use it for more than just SMS and calls.
I know both people that get the latest iPhone every year, and people still on a Nokia 3310(-equivalent), but the latter are in the vast minority in my circle of friends, also in Europe.
Personally, I've been upgrading every 2-3 years (not on a contract), and the phone was never broken.
Gigantic phones are off putting. Every few years Apple tries making a mini and that’s the time to buy.
I’m fairly tall and have size appropriate hands (I think). I struggle to reach the top corners of my 12 mini. It’s very irritating.
And post-paid mobile contracts don't mean that the phone is paid for by the contract.
1) we've used iphone's since the beginning and are pretty loyal, would likely never consider non iPhone
2) we don't tend to switch apps for "inclusivity" as the original comment parent stated. We blatantly exclude people that are not on the Apple product ecosystem by being rather inflexible to even try the universe of platform agnostic options (WhatsApp, etc).
This is my experience in the US. Basically, we're acting like the teenagers except in a not so mean and judgemental way.
