My grandmother worked for a bank for the better part of her life. She used to bring old punch cards home to use for notes/grocery lists. My mom and I used to drive through her teller window and send her cookies through the tubes or the document slot.
I'd like to do this as well. BUT, I have serious doubts that free gmail will be around long enough. Any thoughts on an alternative service? DIY with markdown and git hosted somewhere portable maybe....
The pencil for the Remarkable tablet has this feature. I found that it was a great way to ease into digital note taking. Matching a real-world feature felt very natural.
