A pen is different from the pad, the key, moving your fingers across a screen. I like both. I like to work on sketchbooks, big old white sketch paper. I like how that feels, and I like to put different media on it. Then there's the phone, smartphone, iPad: It's the new page, and it's not the same page anymore.
I want to listen to my Apple Music on my iPhone. I also want to listen to it on my iPad. I want to play it on my Apple TV; I want to be connected everywhere I go. It fits into the puzzle of everything that is Apple, and, therefore, it should not be seen as some sort of separate entity that is trying to find its way.
Look around on your next plane trip. The iPad is the new pacifier for babies and toddlers. Younger school-aged children read stories on smartphones; older boys don't read at all, but hunch over video games. Parents and other passengers read on Kindles or skim a flotilla of email and news feeds.
