It's been 2.5 years and Apple still hasn't sold out of its test run of 500k units. About 350k of those sold in year 1, about 50k sold in year two, and less than 20K so far in year 3. Workers at Apple's flagship retail stores are saying they haven't sold one in recent memories. The tables displaying them are disappearing from stores. Roadmaps for all future goggles have been shelved. It's a flop and Apple knows it.
