I use a pine note + a bluetooth keyboard + SSH / VPN to make that work for me. It's acceptable. I would like "a laptop", but it's fine.

I use a Bigme Hibreak Pro eink phone, nix-on-droid/ssh to home server over tailscale, and a foldable keyboard, to have my coding setup with me and not be tied to where I can carry a laptop.

For foldable keyboards, if they are flimsy or stable matters.
