The problem I have with these boards that pop up is that they get announced, they aren't quite compatible with the popular alternative (the Raspberry Pi), so you buy one and it ends up sitting in a shelf somewhere. I still remember the whole Intel Edison disaster.

These days, the primary decider of which board I'll use is how big the ecosystem is. The Raspberry Pi ecosystem (as well as the Arduino ecosystem) is huge, so that's definitely a big plus. Other alternatives, for example the ESP8266, that are compatible with the "big player" (in this case the Arduino), get this advantage for free.
