Just a few quick notes:

Old devices because the idea is old and the thread developed in time, remote desktop technologies because they work on many more devices and are the foremost traditional way.

Outdoors. You do not bring an LCD-like technology out to fight with environmental light, right? (Well, yes, if pushed, but really.) Plus, if you contemplate a lot - text -, EPD is made for that (bistable).

I'm not concerned about the cursor framerate because I use i3 window-manager (so I usually get around with keyboard hotkeys, minimal-to-no mouse usage)

And where have you found reliable information that the Dasung has higher framerate? Can we see the numbers?
A priori, for Dasung to have an increased framerate, they should have devised a special waveform. That is something one would advertise in detail.

Mouse cursor framerate may not necessarily be a strong hindrance, you can get used to it. Plus, there are ways to use the touchscreen.

The resolution of the Onyx Monitor app is smaller (say 90%) than that of the display: Android software will be crisper, and the graphics coming from the HDMI softened, damp.
Battery consumption values appear as strongly inefficient (say 5 hrs of moderate use) - but you will probably keep the USB cable, hence charging, connected, also because e.g. of touchscreen functions.
EPD screens have a lifetime in dot-switches, but rough calculations show them as acceptable.

Although not a wiki, which may come as people will find the time, I still do recommend that you skim through the 40 pages of the thread. Maybe start when the Max2 related pieces of information start to appear.
