I don't travel for work very often, but as I work remotely I do work out of coffee shops and libraries fairly frequently in order to get some time outside of the house. I have a 2016 13" mbp and I find that its weight and form factor make me much more likely to go out and work elsewhere on a whim than when I had an older 13".

I find the touch bar worse than useless, and while I like it when it works, I find the reliability of the keyboard extremely frustrating given that the machine cost over two grand. But the weight and form factor are things that I really do like about the machine.
