Serious question: what are people building with these boards? The recurring projects I've seen are controlling lights, doors/locks and monitoring water in plants. I don't find these particularly compelling, am I missing something? How is this the next big thing?
The thing is: most of electronic projects needs some way to control things and it is great to take shortcuts. In my case all analog section was custom made to the point of 16bit ADC and used Arduino/Teensy as a way to react to clicks on button, transfer data to computer and stuff like that.
