I would love this.

However, Waveshare whose epaper displays I use a lot always say they are not suitable for working in direct sunlight. Which is kinda the one thing such a laptop would really shine at.

So, would this be suitable?

PS: Front View and Side View show a svelte laptop but the "Chassis" photo shows a Lenovo/IBM T41? I assume this is a prototype and not the actual chassis.

I wonder if they would sell the display they put in those T41 prototypes, I still have a T42 lying around that would come in handy for this.
