What about the Remarkable (https://remarkable.com/)? It's both got a larger screen and it's supposed to have a vastly improved refresh rate. I haven't tried it, but I'm really really curious about it.

It's beautiful hardware matched with absolutely horrid software. It's Android 4.0, which means literally nothing works. They've tried to fix it with custom apps, but I still can't achieve a decent work-flow and there's no community to make it better. It's actually the worst.

That is awfully wrong, it boots a custom linux-based OS, not Android. You are probably talking about other device (probably the yotaphone).

I use the remarkable for taking notes on online courses, and works wonders.

Whelp, they marketed it as Android and it had access to the Google Play store, so I thought it was Android...

Seems I was wrong! I still maintain its very poor for reading papers I've found on my phone and then syncing the annotations.

Omg. I got the goodereader.com 13.3 inch confused with the Remarkable ereader. I have no idea how, but here we are...

Sweet, this is my second stupidest comment on this website.

Nothing shameful about making a mistake, happens to the best of us. But you might want to edit your first comment to point out that you were referring to a different device in case people don't make it this far down the comment thread.

I think the edit button ages out and I've missed the window?

I read books with it and it's wonderful.

Do you have a citation or reference for this? Being stuck on and depending on Android 4 would be a downer but it doesn’t seem to be the case from a cursory look. Or maybe I’m just wishfully hoping it’s not the case.

I have a coworker with one and it seems great and he loves it. I’ve just not rationalized the cost vs benefit to justify buying it personally.

There are e-readers out there big enough for this: the Onyx Boox Max2 and Sony DPT-RP1 (and possibly others). They’re expensive, but if you’re willing to shell out for a dedicated device for this purpose they work well.

It is likely easiest to parse or even semi-manually reformat papers for a smaller screen.

A tool to do that automatically (layout partitioning) would be a nice project idea.

koreader does a really nice job of reflowing PDFs, I use it a lot on a Kindle

In the article's video review they demonstrate showing a pdf nearly full size on the e-ink screen when it's folded over into tablet mode.
