I really enjoy the way that they admitted their design mistakes of the past by having the speaker mention that users love tactile function keys and made it come back. They tried their best to say it was a mistake without explicitly stating it. It's almost like they did real design and usability studies, and then acted on it!

I find it so surprising that in this day, a big tech company is actually listening to its pro user segment (at least more than before).

Fingers crossed for lightning port switching to USB-C, Touch ID making a return to mobile devices (does not have to replace Face ID although I wouldn't care if it did), and the screen notch going away over time.
