>Or jotting down any kind of quick idea I have when I am on the road (frequently).

Seems way too inconvenient compared to opening a notes app on a phone. I always have a phone with me, but there's no way I'd ever bring paper with me when leaving home.

>Or sketching an idea for a screen print or art design.

Fundamentally niche, but if ever wanted to draw anything, I'd get a tablet.

>Or making notes about what groceries to pick up the next time the wife and I head to the grocery store.

I use the cart of the grocery delivery app as a grocery list when going there in person. But if I didn't I'd just make a checklist in a notes app.
