PC World - Project Glass is Google's dream to mass produce hybrid glasses that act as a miniaturized smartphone wired with hands-free access to a micro display, cameras, microphone, Web browser, and speech recognition. It's the type of jaw dropping innovation the tech elite love.
It depends on the quality of their speech recognition (the one on android won't quite cut it), and the price at which they are for sale.
It's the future - the only question that remains is if the technology and its financial state, as well as the public are ready for it.
