I've had the Pro for about a week now, and it has replaced my laptop for 90% of what I do. I can run my small business on this thing no problem. My only concern is music management. I have all my songs in iTunes. Let's say I want to sell my laptop at some point, how do I manage my music then? I do have a premium subscription to Spotify (via my cell carrier promotion), but it doesn't work well in my car. Songs randomly stop playing, playlists are fubar, not a cool experience. Apple music is the same. But normal songs that are within itunes work well. So that's where I'm at. How can I continue managing/adding/removing songs from my iPad Pro (along with iPhone) without a full computer? In my scenario, only actual files work, not streaming.
