So you’re using Markdown cells for notes and not using code cells at all? This is a strange choice. It seems like just writing Markdown in a text editor, Markdown editor, or even an IDE with Markdown rendering would be better options. If you want to output the Markdown to other formats, pandoc is all you need. I’m not sure what advantage Jupyter gives you in this use case.
I want to be excited about this, but I just don’t believe I’ll actually be able to get one for retail price. For much of the RP4 lifecycle they prioritized corporate sales, and regular consumers were out of luck. I don’t have a lot of faith in them right now.
