I'd love something without backlight (front light is OK and encouraged, similar to Kindle) as my main monitor. That would save me from so many of my migraines.
Yeah, it feels bad, e-ink is currently too inaccessible for all but the most dedicated. But at least it's an indication of the beginning of e-ink displays coming to market - albeit it'll be probably a few years before it comes to fruition.
Don't know how to shoehorn this in, but this guy on reddit has taken a deep dive into all e-ink devices for his health (apparently LCD/LED screens cause him chronic pain), and it's been pretty inspiring, to me personally, to keep an eye out on eventually incorporating e-ink into my life. So, depending on your migraines and health prioritization, maybe worth mulling over.
