When will Glass launch and be available for purchase?

Google states that the Glass launch will make units available for retail purchase by Christmas 2013.

Pricing has yet to be announced. You can make your voice heard on pricing by chiming in on our poll : How much would you pay for Glass?

Initially the units will only be sold to consumers within the United States.

Google made ‘Explorer Glass‘ prototypes available for purchase to a limited pool of developers who were willing to pledge $1500 at the companie’s I/O conference, held in San Francisco in June 2012; these units are expected to actually begin shipping Spring 2013.

Google further opened applications to an additional 8,000 Explorers in late February 2013, announcing ‘winners’ in late March. Those selected will be offered Glass for $1500 plus tax, and required to pick them up from special orientation events to be held in New York, Los Angeles, and San Francisco. It is expected that these units will be ready for pickup Summer 2013.
