it's a space monocle.
To be fair, I wouldn't turn down a Segway.
Would you turn down a Segway TO THE FACE?
It should be modeled after dental headgear circa 1975.
I'm just going to straight copy my recent Facebook post about Segway scooters:"I thought I would eventually get used to Segways and stop finding them completely ridiculous. This never happened. They are essentially just motorised wheelchairs for people who can stand. They make as much sense as Fred Flintstone's car. If he's walking anyway, why does he bother taking the car with him? If you're using motorised transportation so you don't have to use your legs, why bother standing? Why not just buy something you can sit on and be done with it?"Google Glass also kind of fits into the 'Flintstones Car' category of technology.
While I don't disagree with your major point, you have to remember that the whole point of a Seqway is that it's a toy. An expensive, hi-tech (more or less) toy. Google glass is much the same. Toys don't have to be practical.However, I do have a bone to pick with you about Fred Flintstone's car. That car is TOTALLY practical.
To Glass Explorers (eg, my mom) wearing glass is like a smart phone on your face. But I can totally get the analogy the dude is making.
