Who needs invitations? You can now buy Google Glass without one

Now you don’t have to be special to buy a Google Glass for yourself. You just need to have $1,500.

Google is evolving into “a more open beta” for Glass, continuing the Explorer Program for early adopters, according to a post today on the Google+ page for Google Glass.

Glass Explorers in the U.S. can now buy Google Glass in charcoal, tangerine, cotton, shale, and sky. And you can even ask for titanium frames or shades, free of charge. The move follows a one-day sale last month.

A “wider release” of Glass is coming, according to today’s Google+ post.

Google has tried to find more ways to show the value of Google Glass, with the Glass at Work program.

The New York Police Department and the U.S. Air Force have tested Glass, and some doctors have already found uses for Glass. Enough of these business-oriented case studies could show the widespread market viability of the wearable device.
