I'm at the 6 month mark on a 2017 15in and I still dislike it. It's not that its terrible...it's just worse than the function / media keys. Its a step backwards. Perhaps if the touchbar was in addition to the old function row I wouldnt mind it as much.
in system settings under keyboard you can set it to only show the function keys and act only as a row of keys (similar to how it runs while bootcamped into windows)
That's how I've set mine up, but even that mode is significantly worse than having physical keys, due to the lack of tactile feedback. I still accidentally touch the software keys without intending to several times per day, and I can't press them without looking at them to confirm that I'm touching the correct one.
You can set that up only per application, and you can't do anything fast like dragging all your apps into the window. You have to click the + button once for every app on your machine and manually select it from an Open dialog. And the dialog doesn't remember the last directory used. It's utterly hostile.
