^oh, did I mention Google Glasses are all the rage now? Glasses are definitely "in"!
I'm really not comfortable with Google Glass becoming a thing. Not only does it have a camera on eye level at all times, it has live streaming capabilities. I wouldn't be comfortable telling anyone a personal story when they're wearing one of those.
People obsessed with their phones is bad enough. People constantly looking to the upper right to view that display would be even worse. It's interesting for holidays and travels I admit, but what I fear is that it becomes 'one of those things'.
