I just came back to my esp32 after a 6 week hiatus and the framework has evolved impressively in that amount of time. It's an awesome product for a steal of a price. Definitely at the usable stage.

That's great to hear!

If that's the case, then it's basically just supply chain issues that's left. It's still hard to get batches and it's probably still pretty expensive compared to the 8266?

That is true, but the SDK is so much better that frankly I don't care, but then I'm not doing high volume products either so thats easy to say.
