I liked the TouchBar. There were two problems with it:
1. It replaced the F keys. I suspect pros wouldn’t have complained so loudly if it didn’t. And it was too expensive for the cheaper computers where it may have been more popular.
2. They never changed it. Ok the first version wasn’t a big hit. Other than bringing back the escape key they never did anything. They sent it out to be a hit or to die and gave up there.
#1 bothered me the most. A lot.
And the stupid thing was that there was plenty of space for a row of function keys and the touch bar.
no2 is what annoyed me the most. I liked it for the most part, but it was never updated, even on the software side we had very few changes. It could've been great.
I would note that Steve Jobs would have probably supported removing the F keys.
See the NeXT keyboards - no F keys. http://xahlee.info/kbd/NeXT_computer_keyboard.html
The ones with the command key beneath the space were nice - except for the help key being so prominent.
