> It might then seem reasonable to think that writing with a stylus on an iPad or similar would be best, since no force is needed and friction is minimized. I don’t think this is true. A small amount of friction is actually desirable.

I find digital handwriting quite pleasant and almost better than writing on paper. Friction is indeed an issue, but you can just buy a dedicated screen protector to address this problem.

Yeah especially for doing math, I've found it's really helpful that I can just select some equations I wrote and shift them down (or insert more space). It helps with adding derivations or additional notes after the fact.

However I'm considering moving back to handwritten notebooks for some things, purely due to the simplicity (no worry about battery life, technical issues, or the difficulty in switching back and forth between my book reader and my notes app).
