Boo, who cares about a cheap iphone that is no better than the old one they are still selling.
64bit ios7 is cool but fingerprint sensor is a bit big brother to me and it's going to be hacked and used to commit crime and be bad press it just will be bad PR.
Most professional IBM laptops have have fingerprint scanners for a long long time. It's secure. And no, it's not going to be used to commit crime. If you're that worried about this, then google voice recognition and facebook's auto face tags probably have you up at night already.
