> Things like touchId were amazing features in their own right though.
Touch ID is cool and all, but in 2016 calling it "amazing" is a bit of a stretch. ThinkPads first got a fingerprint reader more than a decade ago: http://www.technewsworld.com/story/37017.html
So what? The technology doesn't matter -- what matters is the implementation of the technology as a user-friendly feature. Apple did it better, as they often do in these cases.
As a feature, the Thinkpad fingerprint readers kind of sucked. All you could do is log into Windows with them, if you had the Thinkpad crapware installed. They weren't very reliable, either. I had one, and I gave up on using it after a while because typing my password was faster than attempting to use the fingerprint reader several times, then giving up and typing my password anyway.
Touch ID is built in to iOS. You can use it to unlock the phone, and to authenticate yourself for various Apple applications like the App Store and Apple Pay. There are also APIs for third-party applications to accept Touch ID instead of passwords, if the user wants to do that. It is fast and generally reliable. It's light years ahead of the fingerprint reader on the Thinkpads.
Now the best they can do is a second lens for kinda bokeh and adding a touch bar instead of physical keys on the macbook.
