Gary Shteyngart tries to explain what wearing Google Glass is like in the New Yorker. Right now, it's kind of like being a celebrity:

“I see that on TV!” A Park Avenue doorman runs after the man. “What it do?”

“I’m taking a picture of you,” the man says.

“Oh, shit!”

“And now I’m recording a video of you.”

“Oh, shit!”

“Technology.”

“Yeah.”

Shteyngart's the author of Super Sad True Love Story, which is a novel about a future in which Google Glass would not be out of place. If you read Love Story, you know that I don't necessarily mean that Google Glass is a futuristic idea; I means that Google Glass is an idea that could become so ubiquitous that it we use it for all of our dumb, inessential pursuits. You should go read the whole story.
