The touchbar is awesome--you can immediately blow away all the worthless function keys and have a minimalist setup. I keep the escape key and the volume/brightness sliders, that's it. Keeps the entire setup feeling clean. People actually use the touchbar for context-dependent tasks?
Its great for scrubbing through video. Tap and hold for fast, fine grained control. My only complaint with the touchbar is its too easy to accidentally engage Siri. Other than that it’s a good idea IMO.
