This was my gut reaction as well as an eInk enthusiast, but I think the author is looking for something quite different. As much as the rM is a calmer, slower-paced device by design, it's still a device with a screen that doesn't have the same physical affordances and spatial flexibility as pieces of paper.
I agree, absolutely love my reMarkable for those reasons, as well as not needing to manage the _annoying_ physical properties of paper (storage, organization) any more
