Hmm... I must be in the minority. I've almost always hit the Home button to wake up my iPhone going all the way back to the first gen model. Then I'd swipe to unlock. But with my 6s I would still hit the home button, and the Touch ID reader was so fast that it simply unlocked the phone for me, and I didn't ever get a chance to look at the screen. I tried training myself to hit the power button to wake the device instead, but didn't get accustomed to it. Now, I simply pick up my phone and can read notifications. When I want to unlock, it essentially works exactly the same for me as it did before.
