As an amateur pilot flying a very beat-up Cessna 150, I just wanted to chime in and say this is very cool.

I’m not sure how helpful this is as feedback, but I think it might be better to market this as a more general e-ink hardware notification device that can sync with any number of data sources, not just METAR. For example:

- General weather reports

- RSS feeds

- Stock reports

You could then make it developer-friendly so people can easily create new integrations, and over time you’d build up a library of them.
