I like adjusting brightness and volume with a slider. You can tap and hold the brightness or volume icon on the touch bar and slide it to where you want. Repeatedly tapping physical buttons feels vulgar by comparison.
I like seeing the progress and having transport controls of my full screen videos.
I like having the little animation draw my attention when I can use touchid for something.
In general it feels futuristic, fun, and like a way better use of the space than physical keys that I would almost never use.
If you’re someone who uses the function keys (JetBrains users maybe?) I can see feeling the same way I did about esc.
To me, using function keys is un-apple-ish.
I have command, control, and option keys that allow me to be quite expressive without moving my hands away from the home area of the board.
Perhaps those with larger hands can reach the function keys without disrupting their positioning. For me it is not possible.
At that point I may as well reach for a mouse or a touchpad.
