Yes, this is not as fast, but I got used to it quite quickly. I think you need ten finger typing or you might get very frustrated.

Ghosting drove me crazy with CRTs and older LCDs, so I guess this is not for me.

I do not think so no; I am from a CRT generation and I never noticed even with burnt in amber or monochromes(green). If you cannot stand that, eInk won't work for you I guess.

I have an E-ink tablet, Boox Note Air. Some thoughts:

- Screen must be backlit. E-ink screens look great in perfect sunlight and fluorescent lights , but if you're used to a phone/tablet, you'd be surprised how dim e-ink can look just sitting on a couch in the evening, with a lamp a few meters away. Backlighting fixes that.

- Web browsing on e-ink is not bad at all if you stick to text-heavy stuff. The low refresh rate actually discourages "endless scroll" behaviour. Get a browser like Kiwi that allows you to set the Vol. keys as PgUp/PgDn. That makes the lag a lot less perceptible.

I live in places where the sun always shines; it's almost impossible to work normally outside (which is my preferred office) without eInk. I wish there were more laptops because it works fine for coding (I have Boox devices which I use sometimes to write code). Phone same thing. Of course with the great extra of having very long battery life. My wife writes/reads books on eInk devices and I do reading, browsing and s…

Living the e-ink dream. I keep waiting for some sort of ARM powered e-ink laptop to materialize out of the ether, but it hasn't happened yet.

I have a Boox Note Air that runs Android. I imagine the processor is ARM-based. I can hook up a BT keyboard + mouse and use it like I would a regular tablet.

Plus, it has 3 screen refresh settings (low, med, high), and the middle one makes typing a very nice experience

I don't see the attraction of the Mudita Pure (other than a very nice aesthetic). It just seems like a (hugely) overpriced Nokia feature phone.

The Yota phone from 2013 had a regular LCD screen on the front, and an e-Ink screen on the back. I think there was even a Yota 2, but in terms of general adoption, it flopped hard.

There are color touchscreens (Boox has one, there are phones that have those), but yeah I work in monochrome when there is sun or when I run out of battery; it works very well for me. But obviously YMMV! It beats sitting inside or squinting into my Macbook screen by a large stretch.

What about the refresh/redraw speed? I suppose e-ink has evolved past Kindle Paperwhite standards, because otherwise I can't see how you can use it for coding. Turning a page has a terrible redraw speed, it would drive me mad -- it looks like it was with LCD screens when they were first introduced: terrible. It doesn't matter for reading books, of course.

Check out review videos of Boox tablets (speed/X mode) or Dasung E-ink monitors. The refresh rate is pretty good.

e-ink devices generally using frontlighting, not backlighting, which is way better on your eyes.

I use the LightPhone. IMO, eInk takes things maybe a bit too far. The refresh rate is terrible and I have yet to seen an eInk phone that has a good texting experience. Most of the companies doing this are trying to get people off their smartphones (a goal I agree with). But making texting harder ironically leads to me using the phone longer than I would if I had an easy way to send a text. The battery life and visibi…

To be clear, the Light Phone does have an e-ink display. You're not happy with that? https://www.gq.com/story/light-phone-2-review

Correct, it does have an e-ink display and I find it to be very limiting (beyond what's necessary to break bad smartphone habits).

One Laptop Per Child had a transflective display, and I wish they'd managed to license that tech to someone else to help fund the project.

IIRC, with the backlight on you got full color. With the backlight off you got greyscale.

> Ghosting ... I guess

You should try. E-Ink displays refresh their areas using algorithms involving "waveforms", normally at a layer which hides the details, but giving the vendor and user options about how the display will work. The amount of ghosting depends on the "waveform".

I have no issues with ghosting using an Onyx Boox Max2 as a tablet for word processing - which is quite an achievement.

Together with the Pixel Qi you make reference to, there are a number of display technologies available or partially developed for outdoors use. And some are relatively old: has nobody here ever worked with, eg., a Palm Tungsten with transflective display?
