It is not a foolproof form of securitisation against a determined thief. It is a deterrent but there will be some way of getting around it. It's more about preventing unauthorised access to your phone and simplifying the login/authentication process. As a general level of security a fingerprint is actually pretty good.
I have a fingerprint reader on my laptop and it works fine. You get used to swiping the finger to unlock the PC. In the PC's case, you can always go back and use the normal user name and password which means that they can make the make the fingerprint reader stricter. I would hope that they do the same with the iPhone. That way a person can put in a long password as a backup and the reader could require better accuracy.
