"Google has announced a new version of its business-focused Glass augmented reality headset, which it’s now designating an official Google product instead of an experiment. The Glass Enterprise Edition 2 costs $999, although, like its predecessor, it’s not being sold directly to consumers. It’s got a new processor, an improved camera, a USB-C port for faster charging, and a variety of other updates.Google announces a new $999 Glass augmented reality headset | The Verge
Google still isn’t positioning Glass as a mainstream product. But it seems to be expecting greater sales of the Glass Enterprise Edition 2.
