I’m not sure why everyone is so shocked by news that an artist created a cover for The New Yorker using an iPhone app. Big deal. It’s a tool for creative outlet. That’s what it does and therefore we shouldn’t be all that surprised by its use for that purpose.
I have to wonder if these people, had they been around at the time, would have been quite as breathless about a news reporter using a photographic contraption to capture a scene as part of a newspaper story.
