Can someone explain to me, a person that did not have any Apple device ever, what do they mean by:

easier device set-up (e.g. pairing).

So you could not pair non-apple device with your Apple device? And seriously no smartwatch could work with iPhone other than Apple Watch?

If it wasn’t for Spotify, I wouldn’t know most of the artists I listen to now. They might receive little money from me listening to them, but it’s still more than they would receive if I didn’t knew about their existence.
