Would you really replace your specs with a computer? Or wear a camera on your head?
It can only be a matter of time (and maybe not too much money) before Google Glass, or 'Glasses' as I call them, glide gracefully through the classroom doors and onto the heads of every boy, girl and teacher who cannot escape the futuristic amazement of this augmented reality phenomenon.
