Touch ID is one huge disaster waiting to happen. We know how the NSA can get their grubby fingers into pretty much anything through secret court orders and clandestine scheming, and lying to the public (even congress) at the same time.
Quite frankly Touch ID is nothing more than a gimmick IMO, I can do just fine without it.
And horseless carriages were nothing more than a gimmick at the time.
Are you suggesting a connection between TouchID and the NSA - or is it just that we shouldn't worry about security because the government can take any data they want from us? I don't know about you, but I'm more worried about someone snatching my ipad or iPhone when I'm on the train than the gov't digging into my whereabouts. Frankly, I don't have an overinflated sense of self worth to think the gov't really cares who I am or what I do.
And TouchID is not just a way to unlock your iphone or ipad, it will become the way forward for general identification for purchases, banking, etc.
