Always wondered how good the Remarkable series is. Have been tempted but the hardware isn't that cheap really. Since discovering the PDF reader of Zotero and running it with a night mode plugin, I've found myself mainly just wanting to use that. The annotations are stored separately as well, so you don't get massively inflated PDF filesizes (though if you want the option to export with embedded annotations, you can do that; you can also import embedded annotations to Zotero and then clear the file of them). Very cool.
