Nike+ Fuelband: Any one try this out yet?

So we all know Runkeeper and that’s obviously just the beginning. I’m all for getting more easy to wear sensors for tracking workouts, and I realize this is basically just another wrist band monitor and gamification enabler that’s Bluetoothed into an iPhone, but wondering if anyone has tried one of these yet?

Personally, I’m all for more data, and the easier it is to wear the sensors the better. I’ve been using a heart rate monitor bluetoothed to an iPhone and it’s changed a lot of how and where I can do things like HIIT (eg: HIIT a hike) also for tracking thresholds and progress, and most of all for keeping me honest on how hard I’m really going. Wondering what this FuelBand thing does beyond gamifying workouts.
