Google Glass
Ever lost your way while walking in a straight line down a sidewalk? Wanted to take that photo of your daughter's first steps, but just too tired to pull out your phone? Ever feel lonely and just wish you had someone, something, to talk to? Those are just some of the things you can fix with Google Glass ($1,500). Controlled by nothing but your voice, this head-mounted computer has a camera and a screen, and is the closest you can come to a POV camera video game HUD in real life. What you do with it is totally up to you.
