In my day-to-day life, I could see using Glass to snap photos of buildings, animals and even people to learn more about them, though I realize the last one is a touchy subject for many people. It would love to use Glass to navigate inside supermarkets and department stores to find specific products. I can also see using Glass to read me news articles while I'm getting ready in the morning (a feature already available).
