Ask HN: If you code on a beach or at a bar, what do you use?

I frequently go out to code. And it almost always involves bringing a laptop. I think since reading "The Diamond Age" I've longed for some perfect, rollable, e-ink way to just jot down code with a pen on a table. Maybe even before that.

I mainly use VSCode these days. I've experimented with tablets, rollable keyboards, even just using my phone... but it's always a pain. I can't really picture wearing a headset or something. I'm trying to look less like I'm coding and more like I'm just writing. Does anyone have a brilliant hack for doing this currently?
