Google Glass (2013)
Google sold a $1,500 face-worn computer with a camera and tiny display. The price scared off mainstream buyers, and the always-on camera triggered privacy complaints. Wearers picked up the nickname 'Glassholes.'
Google pulled the consumer version in January 2015 after weak demand and steady backlash.
Glass survived only as a niche enterprise tool and became the cautionary tale for camera glasses.
Meta's bet is that low prices and normal-looking frames solve the two problems that sank Glass: cost and the creep factor.
