Google unveils Project Glass Explorer Edition, takes preordes only at Google IO

We've been wondering when non-Googlers could get their hands on Project Glass in earnest, and now we know: the company is opening up pre-orders for Glass Explorer Edition, a developer version of its heads-up display glasses. How much it's changed from the prototypes isn't yet known, but Google has said that it's been steadily working on refining the hardware along with the software. Sadly, the first crack at the wearable technology isn't coming to the broader masses just yet. Orders are only available to Google I/O attendees, and they cost a pretty hefty $1,500 for their release sometime next year.
