Google Glass may save firms $1 billion

My dad is a chemist who does a lot of lab work. Currently he uses an iPhone's basic features a lot: notes, timer, etc. Before the iPhone he used a chronograph.

Glass would actually be a much better form-factor for him, for simple things like timing reactions, tagging which compounds are in each container, and taking notes. It would free up his hands and let him multitask a lot better.
