That's fantastic, thanks :)
The SparkFun ESP8266 Thing Dev Board [0] has a USB-to-serial so you can use a micro USB cable. They're obviously more expensive but ESP8266 breakout boards like SparkFun's Things and Adafruit's Huzzah are more breadboard-friendly an generally easier to work with.
Just be careful not to connect the 5V VCC to the ESP8266, it will probably kill it.
