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…?

Well let's just agree to call it "the most successful smart glasses ever by a long way".

The original iPhone sold 1.3 million units in its first year. I suppose you consider that a massive failure as well?

It's not 2007 anymore. You can't judge a product today with the standards of almost 20 years ago. Additionally, Wikipedia says it sold 6.1 million units within 12.5 months.

The iPhone was not a completely new consumer device form factor. There was a huge existing market for cellular phones, even smartphones with touchscreens. There is no equivalent pre-existing market for smart glasses today.

It is "for a completely new consumer device form factor"

New? “wearable camera with headphones” is not exactly groundbreaking.

Even a new model with a screen would only be semi-new, other AR glasses have existed for over a decade - with Apple releasing a consumer-focused product last year.

Vision Pro is the same form factor as Meta's glasses in the same sense that a semi truck is the same form factor as a moped.

That's why I gave other examples :)
