I just finished my first Augmented Reality app, which is rolling out to its intended users as I type, so I'm a bit biased about this .. but personally I think: AR is AMAZING. I've used the Vuforia SDK, and the ability to track paper with accuracy on the basis of a well-designed customized brand or design layout .. this is fantastic. So my app is to demonstrate how AR can overlay and track over print, and edit print materials smoothly .. and I'll be damned if it doesn't work just great. My next app will be for kids to make planes, in fact. Use the iPhone like a Magic Loupe, print out the picture, get a folding guide in 3D. Oops, I guess I gave that idea away for nothin' ..
