The Touch ID is really neat, and he misses on of the key interactions. At the unlock screen, you can just touch the home button (without pressing) and it will automatically unlock. No more slide to unlock.

This is great.

I suspect I'll start removing my phone from my pocket with my thumb on the home button. As I grasp the phone, I'll hit the home button but immediately release it. Touch ID will read my thumbprint and unlock the phone just as it's coming up in front of my face.

That's a half-second and a gesture I'll save, every time I reach for my phone.
