I know why I started, but not really sure why I still do. Maybe too lazy to learn something else.
My first iPhone let to my first Mac. Why? Because they worked so well together. Adding new Apple products was easy. Even 3rd party products joined in and it was easy.
Not so much any more. Everything is a PITA. If you don't live in the Apple ecosystem every day, they make it a PITA to do anything. For example, I don't update my apps unless I have to. so when I am forced to do so, I go to try and then Apple wants to verify my identity or get a code off my computer that might be 100's of miles away.
Got so frustrated that I went Android. And I liked it. But wife and daughter still had Apple so that made interacting more difficult. Then they came out with the X so I went back. But it is still a PITA dealing with all the crap they now make you do.
