An era, short as it was, is coming to a close. At the end of the day, Google Glass will be no more. At least the Google Glass that is being offered on Google Play Store. It also marks the formal end of Google Glass' Explorer program, which means that the smart eyepiece as we know it is, for all intents ans purposes, practically dead. Of course, Google officially isn't calling it quits on the idea and simply calls this a "graduation" of the device.
