Um, no? Apple Music wasn't even a thing in the iPhone 4S timeframe. You used to buy music in the iTunes Store, and play it in the music player app.

It used to be if you clicked the App Store, and you had apps to update, it would take you to the "Update" tab immediately.

Then they changed it to take you to the main page, and you had to click the "Update" tab.

Then they changed the updates to be under your account; so you have to find this little corner thing and scroll down, wading through all the ads for the new apps you haven't installed.

Books always had a store, but your library was primary. You managed it; it had books that you'd bought, not empty placeholders for books you hadn't bought. There was a store, but it was the second tab.

Now the store is the main tab, and your library is the second tab.

And, as I said, they've now started reorganizing my library, adding "empty placeholder" books in. I don't see Enders Game in my library any more; I see the Ender Series, and if I click on that, I see all five titles, the first of which I can actually read (since that's the only one I bought).

If I honestly thought Android would be any different, I might consider jumping ship.
