Perhaps, the most requested feature from customers is touch ID.
Now like many if us, if you have touch ID on your iPhone, you probably pick up your iPad and put your finger on the home button only to see that it doesn't unlock because you don't have touch ID.
We get used to it so quickly.
Well now with iPad Air 2 there is Touch ID and it reads your fingerprint and quickly unlocks your iPad will, without having to enter the passcode.
And it works with our stores so you can purchase in the iTunes store and the App store.
And it works with the new iOS 8 developer apps that support touch id.
So, you can unlock Evernote or Mint or your Day One journal just with your fingerprint.
