The idea always has been that it's writing on paper with all the convenience of a tablet like syncing your notes. A notebook will feel like paper, but won't sync, an iPad will not feel even close to paper.

I was considering reMarkable when upgrading my ebook reader with note taking capabilities, but it's mostly a notepad with an option for ebooks (and not the other way around) and the subscription model on top of $500 hardware was ridiculous.
