My theory is
People buy it because it “beginner friendly” like it always IPhone 7,8,9,12 or 12s,13s etc than Android confusing line up of names and products like the Fold samasung
And the interface also good for beginner “to the point its childly easy to navigate and feel”
iPhone is so much better. Hardware is much more premium. Even Samsung and Google flagships can’t really compete with build quality. iOS is one of those softwares that “just works.” Everything you want it to do, it does exactly how you expect it to. Very user friendly and intuitive. Much better privacy and security. Amazing integration with other Apple products through iCloud. And in the US, if you don’t use iMessage you can expect to be somewhat ostracized.
