Could you talk more about how you use it?
https://remarkable.com/store/remarkable-2 says it's for taking notes and writing on PDFs. That's not much to go on...
I sketch blog posts for my blog on it. It has pushed me to write end-to-end without distractions because there's no browser tab to check. I also don't end up finding existing blog posts and ending up demotivated.
I download sheet music from imslp and put it on the tablet, I study and annotate the sheet music and use the tablet to read on the piano.
Sometimes I draw on it, too...
