The most important quality of any successful trend (eg windows, internet, smart phones, cloud computing) has been convenience. Which is also the reason why I think Meta Glasses have a real chance to take off.

Also a key single use case that justifies the cost/friction of purchasing a new device.

Meta glasses somewhat justify themselves just for recording hikes/cycles/weddings etc.

Meta Glasses will just recreate the whole “glasshole” response that Google Glasses got, except with a company that has even worse of a reputation.
