My "is it new?" test works this way: how would I explain what's new to my father (who is 74 years old and knows not much about tech). A7, M7, iOS 7, better camera and flash: not much to say. Touch ID OK that's new, but that's not much.

I am sure you can find a way to explain, it is not that hard.

Touch ID is a lot! No more password entering on iTunes. A godsend for someone who has a 26 characters passphrase like me.

If you have a 26 character passphrase, then how are you having an easy time trusting the fingerprint auth?

[davidcollantes]

It is my fingerprint. Why shouldn't I trust it?

[makmanalp]

It's not about your fingerprint though. It's just that cheap scanners are easy to trick and you leave fingerprints everywhere, including on the very surface you scan it on.

[ricardobeat]

Scanners like the one used only work with live fingers, and read geometry deeper than the surface. You're not going to trigger it with an ordinary collected fingerprint.

If you're cautious enough to use a 26 character passphrase, why are you comfortable revealing how many characters your passphrase contains?

[cheald]

Because even if it's just digits and numbers, 62^26 - 62^25 is a non-brute forceable keyspace.

[madisp]

ah, but it is a passphrase, not a password. Limiting phrases to exactly 26 chars doesn't seem that big anymore.

[bennyg]

Good luck brute forcing an iPhone without it locking up forever though - regardless of your semantic considerations here.

[veridies]

It would be kind of ingenious to publicly reveal a false character count.

(A little paranoid, though.)

"The photos look way better" is pretty easy to describe.

[orbitur]

And if they reply that they don't think iPhone 5 photos look bad?

"Dad, it looks better, is way faster, makes you healthier, take much better pictures and you don't have to type your pass code 200 times a day"
