Feedback from Explorer Edition to help fix issues before consumer release
Speaking to BBC Radio 4's "World at One" today, executive chairman of Google Eric Schmidt fielded among other things a few questions about Google Glass. While the shipping of "Explorer Edition" Glass units last week has the new gadget in the news cycle, Schmidt was a bit less optimistic about the availability of a general release to consumers. His official wording was that Glass for consumers "is probably a year-ish away". While Schmidt isn't exactly well-known for giving perfect predictions on products, you have to assume he has some knowledge of the timetable on a consumer Glass release.
This seems to be a bit of a flexible window at this point, however, as previous statements pegged a consumer release for the end of 2013. Surely as more developers get their hands on the Explorer Editions of the devices, the feedback to Google should help with the final tweaking before a broader release. Google I/O 2013 is just around the corner as well, where we could certainly be given more information.
