Have been experimenting with this unusual Dasung portable e-ink display for park working sessions. It's surprisingly responsive—plenty good enough for writing, coding, studying. HDMI driven, weighs about 1.5lbs, sits in front of my normal display (& uses much less power, ofc).

Startup idea:
An e-ink snap-on monitor for MacBook.
The nature of when and where we work has changed.
Imagine if you could do legitimate work for 4 straight hours while sitting in the park.
Batteries are good enough, tethering is good enough. Last step: the screen.

Yes, I think you're right! The Dasung is "fine", really—no additional technical innovation seems necessary—and I'm sure a "nice" version built with consideration for the laptop adjunct use case could absolutely clean up.
