In that half second with touch ID I can be in my phone viewing the same stuff anyway and all using 1 hand not 2.
If apple gave us and OPTION to display stuff on the lock screen we'd all be happy.
It doesn't really take two hands to open the NC. And if Touch ID and launching an app is as fast as a quick swipe from the top then I want to know exactly where you bought your phone because that performance eclipses even desktop speeds.
