Pencil and paper is also excellent for doing math. Get all the distractions out of the way and it’s just you and the problem you’re working on. Figure it out with a pencil and paper and then go to the computer to write the code to implement the algorithm or calculate the result from the equation you derived or whatever else you were doing. Too many kids have such negative experiences with math in school that they never want to touch a pencil and paper again after they graduate. To me, that’s a real tragedy.

I just love the smell of a freshly sharpened pencil made with good quality wood and the feel of it gliding across the paper. There’s a friction and give to it that you can’t get with a touch screen made of hard glass. No matter how good the stylus or what coating you put on the screen, it’ll never have the (cushiony, slightly rough but smooth) feel of a good writing pad or notebook.

And of course it’s fairly easy to digitize your handwritten scribbles, if that’s what you want to do. I just use a scanner app on my phone and take a picture. The app detects the borders of the page and corrects the geometry automatically. I also have it convert the colours down to 1-bit for maximum contrast and to get the background solid white. But that’s only when I need to send it somewhere, otherwise I don’t bother scanning.
