I just derive zero pleasure from reading on a screen.
I see the utility of having an e-reader and have used PDFs in conjunction with printed material but only as a reference.
Fuck Amazon tho, they a Ho.
I forgot to actually post what I was going to but those are e-ink, that's the whole point of them really, the screens do NOT have to spend any power to retain their images and you can read them off natural light, just like paper. I know this doesn't contradict what you posted a bit but I feel like e-ink is very pleasant to look at and the closest we'll ever get to electronic paper, so the Kindle deserves some credit.
I just think Kindles (from the two Paperwhites I've owned) are very limited and processing is fucking slow for a device that only needs to render fonts and shoot it to the e-ink screen, it doesn't even need to refresh the screen 60fps or more like a tablet. Anything other than moving to prev/next page feels cumbersome in it, and you can only read epubs (or pdfs if you like to suffer) and that's it.
Now a Boox Note Air 3, now that's more like it. Admittedly the stylus experience with non-native Android apps (including OneNote) is poor, but it has a native note taking app and a document reader that lets you scribble on top of PDFs and other types of documents (hint:
https://github.com/kudrykv/latex-yearly-planner). I haven't read much in it but I use it daily at work as a planner and note taker and I can't live without it anymore. You can have the device sleep with a "transparent" wallpaper (meaning whatever you were working on stays there legible) and you can program it to turn off after a few minutes (boot is quite fast). So at the end of the day the battery lasts fucking forever, I think I only had to charge this thing 2 or 3 times since I bought it last year with no exaggeration.
It just feels good to write on, and all the extra functionality is a plus.
