Google Inc (NASDAQ:GOOGL) (NASDAQ:GOOG) announced Wednesday that it’s once again making its Glass available to the U.S. consumers. But this time it’s not a limited-period offer. The search engine giant said the Glass will be on sale until the stock runs out. Now anybody in the U.S. willing to shell out $1,500 for the eyewear-based device can buy it. However, you can’t call it a “public launch” because the Mountain View-based company said the sale is part of its Explorer program.
