It was no substitute for function keys, but being able to get close to the screen while editing pictures and using the touch bar to adjust sliders with my finger without looking at the control on screen was A+, so much nicer than cursor keys.

Having a secondary display that was context-sensitive (thanks Better Touch Tool) was super cool.

My point was that power user hackers will find interesting ways to use interfaces and controls. I’m not really interested in the people who tell me it’s useless for them or don’t need it, that’s fine, but I do want to see stuff that isn’t immediately understood or with a predefined purpose, just because it’s cool.
