Biometrics are really more equivalent to a user name than they are a password. Sure, they get used in some applications as a "password" because it's "cool" but it's fair to say biometrics is public information so while many biometric services do their best to avoid being spoofed, they're really more akin to a user name. I'd also like to point out that fingerprint scanners don't work if you need to use then when you've just gotten out of the bath / been swimming. If something is going to replace passwords then I'd want to be damn sure I can use it 100% of the time I need to (baring when I personally fuck up - eg forgetting my password).
