So I was wondering, in this era of technology, with so many tools and options to take and share notes, who does still prefer to take notes on paper?

While I use tools like Trello to list all the tasks with the team, for my own notes I use paper sheets, as I find easier to check on them.
Besides, if I'm stuck with something, I can doodle a bit (I even use a pencil instead of a pen :p)
