That $1,500 price tag for Google Glass Explorer Edition? Perhaps it makes a bit more sense considering that US labor will be used to manufacturer it. According to unnamed sources cited by Financial Times, the first run of production-quality Glass headsets will be built in Santa Clara, California. The reason? A lot is riding on the quality of Glass, and it's likely that Google just wants to keep a close eye on every single prototype that leaves the lab. In fact, it's not exactly uncommon -- the outfit did the same for its ill-fated Nexus Q, and Apple is building some of its iMacs here in the states as well. It's also important to note that the initial batch of Glass headsets won't be high yield, so there's little reason for Google to look overseas with so few units slated for production. Whether or not the lines in NorCal will continue to hum once these things hit critical mass remains to be seen. Read the full story at Engadget.
