The problems with the new macbook "pro" seem to keep on growing. I am really surprised that Apple did not find the connecting to external display issue in internal testing.
I'm somewhat surprised by the whole touch bar thing, other manufacturers (e.g. Lenovo on the X1) tried it before and use acceptance was miserable.
Lenovo did name it "Adaptive Keyboard" and obviously wanted it to change depending on context, but without 3rd party software support it's not going to offer much. You get layouts for F-keys, home, web browsing, and Skype:

And as far as I can tell, it's just "buttons that move around," without any more flexible UIs like the sliders/scrubbers that Apple is pitching. You're making the "no tactile feedback" compromise that everyone hates, and not actually getting much for it.
Use acceptance was miserable because it wasn't actually useful.
