I'm really glad I bought my ReMarkable2 (and Marker "Plus"), as it suits my use case extremely well: replacing stacks of 8.5x11" graph notepads, while adding digitization / sync, undo/redo, select/cut/paste/resize/move, (modest) pan/zoom, etc. Battery life and form factor are great. The writing UX is really something: low-latency, ~perfect hand detection, and the "feel" of writing. Yeah, the software's mediocre, but…
I bought Remarkable 2 and returned it sadly. It does one thing very well which is writing. But not a great tool for reading PDFs. When I figured pinch to zoom was not possible that was it for me. It’s a really polished tool for wiring but they have a lot of room to improve for reading experience.
Although that only helps to zoom in to one spot, if I were to try using that to read a page where the font is too small, having to shift the page left and right while zoomed, it would be a nightmare to read a document.
My gripe is I cannot switch the device to show a PDF in landscape mode. Then at least pretty much all documents' fonts would be large enough, if I use the height of the device for the width of the PDF. Then I would only have to scroll down and only after reading half a page. That would work well, scrolling left-right-left-right-.... while zoomed in does not, unless the page has two columns of text so that I don't have to scroll right-left-....
I use my RM2 mostly as epub reader. For the price - I got the preorder discount - it was the same or even lower as other pure readers of a similar size.
The software does have some weaknesses, for example sometimes I have to edit the epubs and remove some CSS background color because it ends up black on dark gray (unreadable of course), or it has set defaults for font, line height and such settings and I cannot set new defaults so I end up setting those for each and every document I sync to it anew. Still, it's acceptable for me, it's just a few (now muscle memory) clicks. To sync I sometimes have to start the Windows app to which I added a document a second time before it uploads it to the cloud server. That too now is a muscle-memory action. I hope they fix it some day but it's not a deal breaker.
I did a bit of writing and that just works and feels very good too. Other than the base use cases the software is very barebone. As others have pointed out, that's a goal. The device does everything I expect from it, which is just some basic writing and the epub reading. I can send webpages to the device (while it's online) by clicking an extension icon in the browser, which I do for RoyalRoad chapters, for example. WebToEpub creates epub files for entire Webnovels, which have to be uploaded using the Windows app though.
