I used my old ones a ton. I had the original nook and had been using it for 13 years. I finally upgraded to a newer one with a color e ink screen and I like it a lot. It’s a boox ultra tab c. It was pricey so I wouldn’t get it unless you really read a lot and like e ink

I use it for reading almost exclusively. I read 1-2 books a week and a few volumes of graphic novels/manga per week as well. I have poor vision and the e ink is much easier on my eyes than lcd/oled screens. I can read on this for hours but reading on a traditional phone/tablet/laptop gives me eye strain/headache after a few hours. It’s nice to have a screen you can read with no back or front light. I do use the front light at times but I usually have it off

It’s handy for taking notes and annotations. I’ve read it’s good for drawing as well but I am terrible at drawing so I don’t know. The stylus seems comparable to my friends Apple Pencil except you can use the back as an eraser like an actual pencil

battery life is much better to a traditional tablet - a charge lasts 2-3 days usually, can last longer if I keep the front light off and all the wireless radio stuff off. I’ve gotten it to last a week. It’s a bit heavy bc of the battery though

Wrt color it’s a mixed bag. It’s a very handy feature for manga and graphic novels. But the color panels are new tech so they come with issues; primarily ghosting/image retention. After some time I’ve found an ideal mix of settings to minimize the issue and make the color look as good as possible. The boox os also has a little nav ball that can quickly force a full refresh the screen at any point to remove any retained image. But the color is still not comparable to an lcd/oled by any means

Mine is based on a kaleido3 panel. There’s a newer gallery3 panel that has more vibrant color but with a trade off of noticeably slower refresh rates. It’s not actually an eink panel but something called acep; it was more meant for advertisements/billboards so quick refresh rates weren’t a priority. There’s also no real options for a device with it at the moment aside from one that has real mixed reviews and one that has an open preorder with no eta on delivery as far as I know.

It’s also a somewhat capable android tablet but I don’t really get this part. Like you can run YouTube and games and stuff. But i don’t know why you would bother? It’s workable but not nearly as good. The exception to this is web browsing depending on the site. Heavy text based sites work well in Firefox.
