As someone who has been a paper notebook writer for decades, who went through boxes of paper ergonomic for writing a year, low dozens of pens, including fountain pens and ink, and who stored square meters of old notebooks for those decades, paying for every inch- for some users, the R reaches 1x ROI in less than a year.

Cheers.

Yeah for someone who writes that much it could make sense. But for me, I don't write notes on paper, I use it to draw diagrams and visualize things for myself as well as communicating. I use paper a bit like a whiteboard and a single notebook can last me years. The RM looks like a very cool tool but I would never justify the price.
