It depends where. In Spain people use it for that because iPhones are incredibly expensive here compared to the standard of living. What doesn't help is that the SE/e models are also way more expensive than in the US.
As a result it's mainly rich people and tourists that own them. Most people use budget android phones, the kind that still come with 3,5mm jacks. You still see wired earphones a lot.
I haven't found the need for deeper integration with my laptop beyond what KDE connect is capable of, and my Pixel has a high enough resolution that I can't notice pixels :)
