There is a new board that is is smaller than the Raspberry Pi Zero and available @ $7.99. I wrote my thoughts up at the link - feel free to comment there or here!
Very little support. Have you actually acquired one and tested it? I've looked at this online a few days ago. Conclusion was very little technical support.

In case you can't get connected, they may have "turned off their server before leaving for home"

Firstly, in the very write-up I linked, I wrote:
Unlike the Raspberry Pi Zero, we would expect support to be very poor, and also there is no HAT compatibility.
Secondly, as you can see in my forum they've just asked to join my forum as a subboard and have answered all questions so far. My forum is totally independent so this is a good sign.
I would expect them to answer any other questions that we throw their way. Is there anything in particular you wanted to ask them? You could ask in either of the two posts they have so far, or I can ask for you if you'd like an intermediary...
I have no affiliation with the company, direct or indirect.
