Despite not actually being available to consumers, Glass is still the wearable on everyone’s lips (well, faces, eventually). Indeed, there hasn’t been a more divisive major tech product in years, with laws and social etiquette being reconsidered on the fly. But the best tech innovations always ignite heated debate, and Glass’s extremely thorough beta testing is reaping real-time rewards. The Glass 2.0 update is expected on sale this year, with a mono earbud for audio, Google Now integration, a selection of more traditional rounded frames and apps you might actually want to use (you listening, smartglass copycats?), as well as lenses that work for real spec wearers.
