This is the EPITOME of "DORKY" Geek device. I LIKE it. (But probably typical innovative solution looking for problem. And as always it can have some specific enterprise use but maybe not wide mainstream use.) The main part is that it doesnt require frequent re-authentication. So for people who already do that on their devices (who DOES? Who is REALLY using retinal scanners?) then this is a good streamlined tool.
