@hsl I write on the keyboard, on my phone, and on paper with a fountain pen, every day. There's something about a hand-written note that is different from thumb-typing, or keyboarding.
While I form the words in physical print on paper, I am paying much closer attention to what I'm writing; I'm reviewing as I am recording. I also find that writing things out by hand allows me to be concise, to summarize, and to change what I think as I write it, in a way that digital notes don't satisfy.
