When Apple reported Q3 earnings this year, Tim Cook said that the services revenue would be "the size of a Fortune 100 company by next year."[0] Revenue was ~6 billion in Q3, up 19% from a year prior. That comes out to roughly 20 billion a year.

When I saw everyone playing Pokemon Go and buying coins and what have you, I thought of Apple taking a 30% cut of every transaction...

The service revenue really is the strongest case for being a bull. Of course this is just my own personal opinion. I own the stock and I'm long on the prospects. I also love the products. Also so much cash!
