it doesn't mean they are unhappy about it. Or more exactly that a fraction of them can even look for such a feature.

> Second, user accounts are based on e-mails as a rule, which is not unique at all, every user can have multiple e-mails and multiple registrations.

which is a feature, not a bug. Professional account, personal account, cooking-club account, etc.

That's a different issue.

In some countries, in Asia and Africa, a single device can be used by multiple people. Internet cafes are another use cases. And shiny tablets can be also for one family.

device != user != web service

> The main point, if device ID could be available it would provide more great possibilities for users and web-services.

And it would create big challenges in usability and privacy.
