I like how Ben Brooks describes going back to OS X after using an iPad Pro as his primary computer:
It’s like going home to your parents house for the holiday. It’s home and that’s really nice. But it’s also home and that is really chaotic for most of us. So while it is always nice to visit home, you never want to really stay at home. You want to be back at your home.
That’s what the Mac feels like to me now. I really like Mac OS X, and the MacBook, and would have no problems using them, but knowing what it is like to be on iOS only now — with that knowledge — there’s no way I don’t want to be on iOS.
