Google Glass has so far only been made available to a select-group of beta testers, called Glass Explorers, but later this year this device is set to go on sale to the general public.

First-generation purchasers will therefore be doing much more than simply testing a new product; they will be testing public readiness. And some Google Glass users may discover that not everyone is thrilled about the advent of “wearable technology.”
