Why not just pen and paper?

ReMarkable is also a good option for epaper.

I do it from time to time. Usually just some short notes, but it's not the same for me. I like to write on a machine, maybe because I'm typing on a computer keyboard for a long time. But I do enjoy writing with hand more nowadays. Few years ago I've noticed that I do not write with hand at all, everything was on a computer. So it feels good. Combination of handwriting and typewriter works fine for me. Sometimes, when I don't have note besides me, I write some thought on the phone, because I will forget it otherwise.
