Oh the fingerprint sensor FUD, what fun.....<br><br>First, if one concedes that the typical sensor can be easily fooled, I still think fingerprint sensors tend to add security to most phones. That's because I think most users cannot be bothered to hide data behind a decent pass phrase they would have to type on a tiny keyboard. Joe Average is much more likely to adopt a concept that works something like: Swipe one of your eight fingers (up, down, left, or right) (thumbs can be dexterally difficult) and you are authenticates and one of 32 pre-selected actions happens (call a speed dial, open email, open calendar, etc).
<br><br>A more secure mechanism that no one uses is less secure than an "inferior" one that people will actually use.<br><br>But, I wouldn't actually concede that a fingerprint sensor is necessary less secure than a typical password. These days some can be very difficult to spoof. Almost no swipe sensor targeted to cell phones is an optical sensor these days. The common, cheap ones use capacitive sensors. The better ones use active RF sensing, with sophisticated anti-spoof measures built-in.
<br><br>Some of the more advanced sensors even have the ability to securely store keys right on them, and some even have the ability to encrypt/decrypt data for you once you authenticate, with the keys never leaving the sensor.
<br><br>I say all this just to try to clear up some of the FUD. But, I realize full well that suggesting fingerprint sensors is in no way an answer to the security question on the Neo. I don't even think it makes sense to push for a fingerprint sensor to be included in the hardware rev, because there are better things to concentrate on at this point (wifi).
