Having that scanner is not a good enough reason to switch back to an iPhone for me. They gotta come out with something that's really out there and innovative.
Aside from Lenovo laptops and door locks I cannot think of another consumer device that uses biometrics, while not cutting edge it does provide great security and may curb theft
That's a solid question - what MORE can be done on phones? Not much more, unless its something completely revolutionary like Google Glass (which, for the record, I probably would never ever wear).
I want things to work better and not things to be innovated. I want 2-3 day without charge batteries, 10/10 typing on a screen with amazing predictive text or auto correct that doesn't suck, amazing voice recognition where "FIND CONGEE QUEEN" isn't too hard for google or siri, and so forth. So, like the BASF commercial, make things BETTER.
BASF made some awesome floppy disks.
There was another 4G phone that came out two years ago (can't recall the name) that had a fingerprint scanner so this is nothing new. A Motorola phone also had it and the company eventually gave up on it because of customer complaints.
Personally, if you plan on locking your phone with a fingerprint, good luck to those parents that always pass off their phone to their kid(s) to keep them busy. You'll *always* have to do the unlocking for them now.
