It's a shame that that the list doesn't translate well into "what device can I go out and buy"? Every shitty manufacturer has to constantly churn design changes, and hide it all behind the exact same model number.

For simple PC unlocking etc. they are perfectly fine and improve security due to their far higher usability.

The same way 10 key files on 10 different locations combined with this and that are more secure than a simple 60 character password. But the simple password is far more practical, so far more secure overall since people actually use it.

More secure legally. You generally can't be compelled to disclose a password that incriminates you (unless it's already apparent that you're guilty of wrong-doing) but a thing (physical key, fingerprint, etc) isn't protected in the same way and can be demanded by the court.

Whether biometric are secure or not is another question, they can be stolen like any other data or a motivated attacker could just take you or your fingers.

Biometrics plus a password is even more secure.

I'm not sure why the down votes. You are completely right
