I also got enthusiastic about them, but I ended up embracing the Kindle Scribe. I just completed my 12th monthly notebook, so I’ve been at it for over a year now.

I was using regular notebooks but I was collecting too many and I was worried about storage and loss.

I wrote about the experience a few months into it.

I do not read on mine, it’s exclusively for writing. Possibly because switching is too slow.
