Google glasses to hit shops this year or early next year

This week, Google announced plans to invite 8,000 users to test Google Glass, which have already been available to developers for $1,500, and are expected to hit stores later this year or early next year. The device is the most high-profile example of the latest Silicon Valley trend: wearable computing. For its part, Apple is rumored to be developing a computerized watch product, but unlike Google Glass, no one has seen the device in public.
