Ha, well said!

I have grown to love the touch screen on my Chromebook pixel. Felt awkward to reach at first, but a non touch screen now feels really awkward. Not that the touch screen replaces all interaction, there are some things that are faster on the keyboard, touch pad, or touch screen.

That said, touching other people's screens is not polite.

With regards to the touch bar, seems like you could use software in combination with the existing touchpad and screen to do something similar. Reserve the top edge of the touch pad, on touch a menu pops up, slide to select or something...
