TL;DR
The heads-up display has left the cockpit. Glasses that lay graphics over the real world through clear lenses, pinning windows and labels in place in a room, are now in buyers' hands in first-generation form, and a second wave arrives in November. They are heavy, pricey and run a few hours, and almost every pair of smart glasses sold still has no screen at all. But the screenless glasses are selling fast, the display versions are growing faster, and the big platform companies are all lining up. If the weight and battery problems give way, the phone screen could start moving onto people's faces before the end of the decade.
