Although it looks really cool in demos like this, I personally wouldn't care that much about the video sharing, but I still think Glass is one of the coolest products Google has ever worked on. There's just so many uses for it, and many of those things a phone can't really do well. I think the killer app for me would really be "subtitles" while talking to somebody in a foreign language. Guess a lot of people would only use the contacts-version though ;)
