"Apple's services category continues to grow rapidly, and in the first fiscal quarter of 2018, Apple services, which includes iTunes, the App Store, Apple Music, iCloud, Apple Pay, and AppleCare, saw revenue of $8.5 billion, up 18 percent year over year."
This is huge. Apples services are almost 18% YOY with 8.5 billion in the green. This is where the real growth is for Apple, through services with Apple Music and iCloud, etc. I don't think Apple gets recognized as much as they should in this department Over hardware sales.
