"Now, Google emphasized — and so do I — that Google Glass is still at a very, very early stage. Lots of factors still haven’t been finalized, including what Glass will do, what the interface will look like, how it will work, and so on. Google doesn’t want to get the public excited about some feature that may not materialize in the final version. (At the moment, Google is planning to offer the prototypes to developers next year — for $1,500 — in anticipation of selling Glass to the public in, perhaps, 2014.)
"When you actually handle these things, you can’t believe how little they weigh. Less than a pair of sunglasses, in my estimation. Glass is an absolutely astonishing feat of miniaturization and integration.
"Inside the right earpiece — that is, the horizontal support that goes over your ear — Google has packed memory, a processor, a camera, speaker and microphone, Bluetooth and Wi-Fi antennas, accelerometer, gyroscope, compass and a battery. All inside the earpiece."
