I'm glad the article mentioned ReMarkable. Mine arrived about a month ago and I love it -- carry it everywhere now. It's done a great job of taking care of my need for scratch paper to jot notes on, and it's really kind of an improvement over keeping track of lots of bits of paper or having a separate notebook.

It's so far the best of both worlds of paper and electronics.

Bit pricey though.
