There are some technological developments that come as a complete surprise, and some that are logical extrapolations of what we've had for a while, so obvious that we know we'll eventually get them, it's just a matter of the development of the necessary components. A wearable augmented reality device falls into the latter category. For years, we've been seeing sci-fi movies in which a character looks out at the world, or at a person, and sees a whole bunch of information pop up in front of his eyes (the best-known example is probably The Terminator, which came out in all the way back in 1984).

Google Glass, which is essentially a smartphone in the shape of a pair of glasses that are, depending on your perspective, totally cool-looking or remarkably dorky, is going on sale. You won't be able to go down to Target and buy a pair, though; for this first run, you have to actually apply to Google, and if they decide you're cool enough to own one, they'll allow you to pay them $1,500 and you can start living your augmented life.
