OK, total newbie question here. But what can I do with this? Is it just a wi-fi module? What would I use it for? How is it powered?

It has an onboard ARM micro controller that can be programmed with Wiring just like Arduino. It also has its own REST API for simple web app type uses and has serial analog and digital io pins

It's an ARM microprocessor and wifi module. It's powered via its USB port or whatever you hook up to the vin pin. It's basically another cheap embedded platform, but it's got built in wifi. I kickstarted the Spark, and really love it, so I preordered a couple of these. Looking forward to it!
