One other big point that iOS users don't have the same freedom of choosing other merchants to purchase music on their devices. Purchases made and downloads made in iOS from 3rd party services are not added to your music library to play, unlike Android where any app can add music to your library and any app can play it. So, any band/label deciding to remove their music from iTunes because they'd rather not forgo a full quarter of revenue will lose out on a good percentage of iOS users.
