Doesn't pretty much all professionals from programmers to editors to musicians _still_ use function keys as part of their workflow when touch-typing?
I mean if the touchbar was above the function keys it would be an added bonus, but removing function keys for "professionals" is like telling a pianist that he now has to play on a touch-keyboard with no tangents.
I am more than ready to pay for an upgrade but now i am going to keep my still excellent 2014 pro with no stupid gimmicks and a good keyboard.
EDIT: To all the people downvoting me, why? Why on earth earth downvote a fellow pro addressing an obvious downgrade - am i missing something? Why jump on a bandwagon an "be an optimist" or "stop complaining" if this gimmick makes coding/working slower for us?
It reminds me of when most of the pro market fled the revamped Final Cut X Suite which was so dumbed down it was almost a "kids editing program" while Apple gave no fucks.
EDIT2:
To all the people saying they don't use F keys. I simply don't believe you. You also control brightness, volume and playback with these buttons and i have never seen anyone NOT using these keys without looking. Especially the volume keys all the way to the right tap-tap-tap without looking - i know you have done this ha!
