I love my reMarkable.
I've only had it for a little while, but it's such a useful little machine. I got it for cheap on eBay, and I was sold by the idea of an e-paper drawing tablet. That might be the least interesting thing I can use it for.
Do I need to fill out a form? Well, normally, that would sit for days, because I find it impossible to walk to and subsequently fight with the printer. Instead I can send the PDF to the tablet with a click and then fill it out there. Do I want to draw something? It's easier than carrying around a sketchbook. Do I want to read something? It's more durable and lightweight than any of the books I own. I have an Articles folder on it that I use as a substitute for my reading list, because it's something I'll actually remember to look at.
This little tablet does the jobs of a printer, a drawing tablet, multiple apps on my phone, and an e-reader, and, having gotten it used, for less than those things combined. If you're looking to get an e-reader or anything of the sort I cannot understate how useful it and devices like it are. Even if you don't want to buy a remarkable, the combo of e-reader with a pen is so rediculously useful that anyone looking to get a regular e-reader should look into options more like this.
Anyways, just got done doing significant portions of my college application on this thing. I love it. That's all.
