Tim Stevens, opening his Google Glass review at Engadget:
Smartphones are amazing things, but for those who have become addicted to messaging instant gratification, they are a bit unwieldy. This annoyance gets even worse as these devices grow larger and larger. Well, certainly one approach would be to relax a little and stop feeling so compelled to check for Facebook notifications every 30 seconds. Those fully immersed in the information age, however, will be more inclined to fix the physical inconveniences presented by the problem. A heads-up display seems like a natural fit, and thus we have Google Glass.
