With so much note taking apps nowadays, I can't understand why does anyone still write notes with pen and paper. You need to bring the notepad, book or that paper to retrieve that information, and most of the time you don't have it in hand. While my phone almost always reachable and you carry when you go out. For those still like to do handwriting, there's many app does that and they can even convert it to text notes.
So, if you still write notes with pen and paper, why?
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.
