The only downside is that undo seemingly has gotten a bit slower, so it's often much faster to erase than undo.
Except for that I really like it.
It's expensive but I think it's well worth it and it has definitely replaced paper for me. I also expect it to vastly outlive an iPad or Android tablet.
It is a very well done product, quite satisfying to write on, useful as a reader, successful at syncing.
But the extent to which I use writing as a memory-enhancing practice became clear to me when it stopped working when I used the Remarkable for writing. My observation was that not being able to physically page through prior writing meant it was down the memory hole. Paging through a digital device is too absent context.
I am back to the levenger circa paper and zebra pens.
EDIT: Sony has also released something similar. https://www.sony.com/electronics/digital-paper-notepads/dpt-...
