The Touch Bar implementation sucked but I'm going to defend that attempt 100 out of 100 times. If Apple didn't remove the function keys I think it would have been a hit feature. There wasn't proper commitment to the feature.
Curious why you liked it so much. Removing the fn keys was a big no-no, yes, but also it was just located in a place I'm never going to look at. So why do you think it would've been a hit feature?
True, if they'd kept the function keys and just added the touch bar above it it would have been great. Weird thing is there was more than enough space for both so I don't understand why they didn't do that.
