With Apple's claimed "1 in 50000" probability of a random finger triggering a false positive for TouchID I'm surprised there haven't been over exaggerated reports of failure of the feature. I'm perfectly fine with that number, it's not realistic to ask thousands of people to try their finger (and would of course lock out and require a passcode after just five attempts) to unlock the phone. It wouldn't surprise me to see it make the news when or if it happens and be blown waaaaay out of proportion. My prediction: consumer reports will just happen to be one one where "in our tests a coworker was able to breach" and they'll say they can no longer recommend the phone. It wouldn't be often, but if everyone asks one person to test it there should be 20 breaches per million sold..
