Bluetooth headsets are effectively a punchline. Google Glass—in its current form—is even worse. Until that enormous blob hanging out in front of the wearer can completely fade into the frame this will be nothing more than a geek curiosity.

I think Google has excellent engineers, and very poor self-restraint. This product is at least 2 generations away from what it needs to be, but instead of working on it in the labs quietly and diligently until its ready, they trot it out proudly. Beta obsessed indeed.
