I’ve had an iPad since 2013, and went through the phases of thinking it was awesome to unnecessary. Then I was gifted an iPad Pro last year with the Apple Pencil and everything changed. It’s now my favorite Apple device by far, and exactly for why the author describes; it’s become a digital canvas that enables an input function unavailable anywhere else. If you’re skeptical, you really need to try one out for a brainstorming or creative activity. (Yes, I know that paper still works for this, too.)
