I've wished for years that there would be an actual e-ink only laptop. Or (even better) an aftermarket e-ink screen for my current laptop, because I'm quite happy with the rest of the machine.
Are there any e-ink displays with a reasonable enough refresh rate that aren't exorbitantly expensive? I know atleast as of a few years ago that was one of the issues that would've impeded an e-ink only laptop
From what I read some time ago, e-ink displays use almost as much energy as normal displays if the contents change all the time. The one benefit of e-ink is the ability to show static content without using energy.
That is probably another reason that e-ink laptops haven't really become a thing then - practically any use besides maybe basic web browsing and emails would require a decent refresh rate to be reasonable, removing the benefit of using e-ink over the normal display
