I'm of mixed opinion on it.
It took a while to get used to using it every day. Now I'm OK with it, except for the arrow keys.
My biggest problems are that there are no landmarks for your fingers. I swivel between two or three or four computers when I work, and coming back to the MBP, it's hard to re-center my hands without looking. On earlier MacBooks, I think my brain used the inverted T arrows, because my fingers seem to go there first.
I like the touch bar, but it needs more support, and more consistent support. Even from Apple, itself. Sometimes I can authenticate with a fingerprint. Sometimes not. Sometimes confirmations are on the touchbar. Sometimes not. It's an inconsistent experience.
All of these problems will become moot in a few weeks anyway, since I ordered a proper full-sized Apple Bluetooth keyboard, trackpad, and riser. I miss my F13-F19 keys more than I like the touchbar.
