Mensioned in this interview: https://www.keyboardmag.com/artists/cory-henry-the-sound-of-now "The iPhone 6 is still a good size. It still fits in my pocket. I don’t got that “big old bulge.” So I’m not getting rid of this phone. I’m going to ride it till the wheels fall off!" - Cory Henry, https://www.keyboardmag.com/artists/cory-henry-the-sound-of-nowmore
Okay, the form factor of the iPhone 6 is terrible. They even made the mistake of putting the 'exit' button right where you put you thumb when making a picture. But it OS is perfect. That's why I still prefer iPhone over Android.
What would you do without your smartphone on you? No music anyway. It's great for recording your ideas with the Memo app, composing with GarageBand, making snippets with iMovie, or writing a story with Notes. An idea bag in your pocket.
