Well, a number of years ago, my wife asked me when a building had been built. I thought, "Just click on Help/About and look at the copyright date... Oh, wait. I can't do that on a physical object." But with VR, I could.

Now, I'm not saying that I think that VR is the next big thing. I would pay approximately $0 for the ability to know when a building was built, and I've only ever wanted to know (even mildly) once.

Too many to list. Let your imagination loose. :)
