I suspect once the tech is good enough, it could become quite useful for non-entertainment uses. E.g. viewing houses before buying them, or house designs before building one. Maybe integrate it with something like Google Maps street view, so you can get a feel for where something is, and where to park, before you arrive.

I'm sure there are plenty of other uses, but it will probably be a while before the tech is good enough to be convenient for these uses.
