It’s interesting, because for my iPhone that is true. I was a bit concerned with the walled garden, but made the switch from Android because of privacy (not that Apple is perfect, just much better than Google). I can’t recall a single time when i wanted or needed more than what the iPhone offered.
But with my iPad there are multiple times when i wished i could run a local web dev environment, or run MacOS apps (it is using the save M1 as my computer after all)
