IMO the Touch Bar is pretty useless for serious work. The thing is, you have to look at the Touch Bar to use it! I don't know how you type, but I never look at the keyboard when I'm typing. Plus where I rest my hands on the machine, they tend to touch the Touch Bar, and you can't feel when you are actually touching it and mucking things up.

(Disclaimer: I have a MBP with Touch Bar, but I do 95% of my interacting with it with an external keyboard and mouse because I hate the keyboard / Touch Bar so much.)
