Google Glass is finally here -- almost. While not quite ready for general consumers, the big G's released a new video demonstrating all they can do to tide you over until they're launched.

Wearers will control them using their voice, opening communication by saying "OK, glass", and making a command. It'll do everything from provide GPS directions, to record skydiving adventures, to let you video chat while piloting a plane... all while making you look a whole lot cooler than you would with a Droid taped to your face.
