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.
