I'm still convinced it can be bypassed easily by the hackers as soon as it's released, but I'm pretty sure anyone who went through that trouble would be able to unlock the touchID just the same. I'm really, REALLY not looking forward to dangling the phone in front of my face all the time just to be able to check something. Nor am I too happy about it watching me all the time. Especially considering what that'll do to the already-crappy battery life.
