Tuesday, for the first time, Google Glass was made available to the general public. As part of the one-day-only offering, anyone in the U.S. could buy the $1,500 face-mounted computers and get a free pair of glass or sunglass frames. Google isn’t sharing any sales numbers for the day, so it’s difficult to divine how successful its first open-sales event has been. There have not been reports of the Google Glass sales site crashing or customers being turned away.
