This guy reviews all kinds of e-ink devices. https://www.youtube.com/c/MyDeepGuide/videos
I watched his videos before deciding to get a large format BOOX Max Lumi (13") for PDF reading and note taking. I wanted the large one to split screen a PDF textbook on the left and notebook on the right. That was a few years ago, though, and I suggest reviewing some more recent videos to get an idea of what the current devices are like.
I've found this to be true in general once I started working. I don't feel kinda this was a thing when I was and was integrating with other students. I had to readjust my "responsible" self who actually would follow up (to people's horror) and tell myself it's a polite saying that people don't mean. Like when people greet each other with "How are you?", they generally actually do not want to know how the other person is doing. You're expected to say "fine" or "good" and deviating from that is violating an unspoken social contract.
