The only thing with mobile marketing is that it limits your reach, so if you can show part of the campaign in print then you fill some of that gap. I admit I haven't seen the print ad in person and I haven't actually tried the app out so I don't actually know how successful it is or how easy it is to use. That said, from what I can tell it looks pretty cool. Plus, it is from VW and they usually have very clever marketing (I know that isn't a very good reason, but I'm going to go with it for now).
Let me know your thoughts.
