For people who want to use apps for productivity, it's an intriguing idea that's never really caught on: plugging a phone into a USB hub to add a keyboard and large display, essentially transforming it into a portable desktop. And the reason is probably that you can't just go anywhere and find a USB hub, keyboard, and display already set up and waiting. DeX has a niche following. However, smaller Chromebooks with high-resolution touchscreens and Android apps have filled the void quite nicely. And PWAs are making the same apps available to Chromebooks even w/o running Android. The more tablet-friendly apps become, the more Chromebook friendly they become. Chromebooks now come with a Phone Hub that automatically connects to the phone via Bluetooth. Longer term, that seems to be a more natural way of maintaining transparent access to phone files and communications while working at a desktop.
