I hit a touch bar function accidentally at least once or twice a day. It looks cool, but the functionality is garbage.

I couldn't get used to it at all. Every few minutes I kept increasing the volume or decreasing the screen brightness, and at first I never realised why until I looked at how I rested my hands on the keyboard. A few days after I got the laptop I just got rid of it by taking out all of the touchbar buttons in the system preferences. I would have prefered the function keys a lot more.
