It might not seem like it now but the Touch ID fingerprint scanner has potential to be a real game-changer (assuming it works reliably, unlike Siri). We live in a world of multiple devices, countless apps & social networks...remembering all those logins and passwords is a huge pain in the ass.

I'm reminded of this every time my parents have to call me from the Philippines because A) they forgot their password or got locked out of their accounts for too many failed login attempts.

Identity & Authentication are two things that are due for innovation, and Apple just made the first step towards improving that for mainstream consumers. It might not be a feature that'll make your jaw drop or impress you, but it'll be something you won't be able to live without once you've had it.
