Compare it to devices with similar form factors or use cases sold by competitors:

- Snapchat - has been trying for a decade and has sold ~220K Spectacles.

- Amazon Echo Frames - Reuters estimated less than 10,000 units sold.

- Humane AI Pin - the less said about it the better.

- Google Glass - neat but way ahead of its time, and barely made it to consumers before being quickly discontinued.

- Hololens/Magic Leap - both duds.

- Lengthy list of startups with smart glasses and other wearables that have gained no traction.

Meta glasses are noteworthy because there's finally a company making an AR wearable catch on among a mainstream audience.

Or they are all failures, including Meta’s…?
