Re: Incremental?
Well it takes 2 seconds.
But that's not the point. Finger scanner is strategically much more than pattern swipe on Android:
1. Nobody but you can unlock your phone. No one can copy your finger print, unlike pattern swipe, which can be gazed upon over the shoulder.
2. Touch ID can be used to purchase iTunes content, potentially used later by 3rd party apps to purchase items from their own e-store front. e-Wallet, is the big idea.
Pattern swipe? Google will copy Apple on this one in no time.
