At the risk of sounding silly a few years from now, I'll draw connection to when personal computers were first coming out. It was hard to predict all the uses we have today, and spreadsheets were thought to be one of the killer apps. Similarly, photos and sharing is the obvious killer app with Glass right now, but that's because it's very hard to see that far ahead. I can't wait to see what masses of developers will come up with once it's out for a while.

Further in the future, the device will likely shrink to, or work with a contact lens. At this point, this is not even a question of science, but of engineering [1].
