The more I see Google Glass, the more viable an idea it seems to become. At first, the concept seemed intriguing, but impractical and not altogether useful. Then it evolved into something that could have some potentially useful applications, but may be more of a gimmick. Now, after the last few demos and after seeing this newest "Getting Started" video, I am fully in the camp of, this could be something very cool and potentially game-changing. The video very clearly shows some of the ways in which you can interact with the device. If they can pull off the Augmented Reality real world information gathering HUD (Heads Up Display), then they will nail it's "killer app" functionality and it could be the hot new device of next year. What do you think?
