I code on mine frequently. Using working copy and buffer. With git push and ci/cd it’s a great experience.
What’s buffer? ( I’m getting no relevant search results)
sure, you can expose your workstation with a vscode tunnel and access stuff via the web.
Seems overkill to get an M4-powered device to use as a dumb terminal.
Not really. But you can remote into a real computer.
So a windows tablet would make more sense?
Why not an Android with termux? I guess it would depend upon your software stack, but my editor (Emacs) will have native Android port soon and I am stoked to try it. The latest Snapdragon processors are fairly powerful (and Mediatek/Dimensity ones aren't lagging behind either).
