What are realistic, everyday use cases for Google Glass?

A Real Estate Application that shows rental/sale details of in-market adjacent properties, as the user walks/drives past the area. While convenient to use when driving around an area of choice, it’d also allow a quick benchmarking of relative costs of adjacent neighborhoods. I haven’t yet seen anything similar in the current list of Google Glass applications.
