You’re right on all counts. It is not cheap and easy to migrate away from apple, and some apps may not have an equivalent.

I’ve been anti-apple most of my life for multiple reasons, and I still am, however my work uses apple products for the employees so it just made sense to have my own as well. I deeply recognize the walled garden Apple has created, and the only products of theirs we use are those associated with the mobile devices. We buy nothing else apple; no laptops, no desktops, no backup, TV, etc.
