I don't know about this device specifically but this is a decent review and this kind of simple epaper screen seems like a thing a lot of people would like and it wouldn't become an obsolete gadget being such an inherently simple focused tool.

Feel free to recommend alternatives!

The TRMNL X has been running without recharging showing a single static image for well over six months. It might be approaching a year.

I mean, if it's just a single static image you can go ahead and unplug the battery, e-ink doesn't need energy to maintain an image.
