Never really thought about the usefulness of a fingerprint sensor until I thought about it like this.

It takes 3-4 seconds to home button->slide to unlock->enter in my pass code (longer when I was on alpha numeric.)

I probably unlock my phone ~50 times per day which equates to roughly 200 seconds of unlocking my phone or ~3 minutes per day wasted accessing my phone.

Across an entire year that is ~1,000 minutes or 18 hours I have spent unlocking my phone which is ~$5,400 in lost productivity.

Of you can think of it as 1000 minutes of finger exercise you miss out on. Apple is making us lazy.

- Remotes so you don't even have to move to do things on your Mac.
- multi touch trackpads/mice so you do not have to move your hand, only your finger to move the cursor on screen.
- Multitouch gestures on iOS devices can do many things in one swipe
- And now one touch and you're into your iOS device. No more using moving your arm and hand to put in the passcode everytime.

Apple is good at a lot of things, but making you a lot more lazy is one bad thing Apple is doing.
 
Hopefully when iCloud keychain gets activated, that will resolve having to type in passwords, credit card numbers, billing/shipping addresses, etc .. both in iOS and OS X.

And interestingly, the headline of the article you link to is a little more optimistic. LOL
"iPhone Developers Won’t Get Fingerprint-Reader Authentication Option — For Now, Anyway".
(emphasis mine)

What's the icloud keychain? I'm assuming it's something that holds all your passwords and lets you enter in a master password, or in the future maybe the fingerprint sensor?
