Here’s my experience, I have been using it to read pdfs and it has been great and everything renders fine

The only thing i hate is that it lacks search feature through the pdfs otherwise its has been great and it allows me to stay focused

I've heard that technical books and pdfs don't always render well on e-ink devices. Is that just for kindles which do their own conversion on pdfs, or is that true of most e-ink devices?

PDFs render just fine on a remarkable. Everything is grayscale, but I haven't noticed any rendering oddities.

Hmm, this is something I would like to know as well. I have been interested in e-ink ever since my first gen Nook (my only ever e-ink device, which was poor for reading PDFs).

The no-glare aspect is appealing. It gets tiring reading in dimly-lit rooms.

I have been leaning this way, even before my iPad got broken. I will definitely take a closer look now.
