This seems to hold true for most people. One of my close friends (a successful founder) was an early adopter of the iPad Pro, and intended to make it his go-to device for traveling. He ended up buying the Magic Keyboard case, a USB-C dongle for HDMI out, and the Apple Pencil to comprise a proper Rube Goldberg travel experience.
After months of suffering through that, he switched back to a Macbook Air and carries the iPad for watching Plex now. I am still baffled as to which "pros" the iPad Pro is targeting.
