This is second hand info, so sorry if it's totally wrong, I'll edit this:

E-ink tech is great, but patents and other paper-limitations are slowing down developments of cheap e-ink devices devices, and e-ink will become "great again", when patents expire.

I personally see many, many usecases of e-ink all around me, but the prices are way too high for anything that is not either really small or a repurposed old existing device (eg. jailbroken kindle)

So what's the over-under on E-ink replacing our current computer monitors much like we've come to replace cathode ray tubes.

People have slowly become accustomed to high refresh rate displays.

So that's a big no on e-ink displays unless they manage get them to 60Hz+ somehow

I've been waiting for e-ink displays to become affordable since the first Raspberry Pi came out.

I'm still waiting.

I'd like a dual-layer tablet screen. One layer is e-ink for reading, the other is a standard OLED screen. Since I'm wishing, I'd like it to be 16k and something like 1200dpi :)

I want to hook up a small e ink screen to a pi and use it with my mechanical keyboard as a modern typewriter of sorts but the prices on eink are so prohibitive it doesn’t seem worth it.

Monochrome. It has "turbo refresh tech" but unclear what that really means; with e-readers, similar verbiage just means it's less bad. The resolution and pixel density is very nice. The prices would have to come down by at least a factor of 3 though, IMO. I'd take the under.

Basically impossible. They could be great niche monitors, for reading text or viewing mostly static content. At best maybe for kind of general web browsing, but even that is asking a _lot_ of the tech.
