"Nobody writes articles or does deep knowledge work with smartphones."

I don't think that's true.

I do most of my reading on a smart phone - including wading through academic papers, or reading full books in the kindle app and jotting down notes in the digital margins.

A sizable number of my short form blog entries are written on my phone, and my long form writing almost always starts out in Apple Notes on my phone before transferring to a laptop.

Predictive text and voice dictation has got good enough now that I suspect there have been entire books written on mobile devices.

Whether you want to consider it "deep knowledge work" or not is up to you, but apparently a lot of Fifty Shades of Grey was written on a BlackBerry! https://www.huffpost.com/archive/ca/entry/fifty-shades-of-gr...
