Touch Bar is a nice incremental advance. Not having a physical ESC key is not as bothersome as I expected. In fact, I don't notice it at all. Disclaimer: I don't use vi.
I like the media control modes, and am looking forward to content creation apps (ex: Ableton) making use of it.
I'd be sad if it were taken away, but it wouldn't prevent me from getting work done. It's a nice-to-have extra.
Also, the new keyboard is fantastic. I love the keys, and my external keyboard is now a buzzkill and I can't wait for Apple to refresh the Magic Keyboard with the new switches.
I have never accidentally hit the touch bar.
