Something interesting about the author's choice of the iPad Pro as a replacement productivity machine I don't think gets enough mention is that the iPad is one of the only modern computers of any sort with a 4:3 screen. Closer to square maximizes screen area for a given maximum or diagonal dimension, 4:3 is close to the human field of view, and in general, I find it to be a more suitable aspect ratio for most tasks than 16:9 or 16:10. I'm pretty frustrated and a bit confused by the dominance of 16:9. The fact that it's the standard for TV shouldn't imply that it becomes the standard for laptops.
