One significant reason ESP8266 based devices are taking off is due to the fact that Arduino libraries have been created and are well maintained.
Sonoff Wifi Switches, which are based on the ESP8266, are getting a lot of attention and for good reason. They are cheap and very hackable. I should mention that Sonoff has its own cloud service for controlling these wireless switches
Here is my take on hacking the Sonoff.
