Yes. It’s faster, I have an easier time remembering stuff that I wrote by hand instead of using a keyboard, I can’t be arsed to use a phone most of the time, and I can even apply some primitive “encryption”* to keep a certain overly curious person around me from messing with my notes. I can also use them when I’m designing writing scripts for constructed languages, way faster than doing it in Inkscape.
The big con is that one of my cats thinks that paper is toy, and the other thinks that any large enough sheet is a bed.
*it’s just Italian with ad hoc Cyrillic. Good enough for handwritten notes.
