Picked up a refurbished kinect from Ye Olde Best Buy today. After many hours of frustration trying to get OpenNI working with my computer, I finally found a tip online that pointed me to a capitalization error in one of the environment variables.. SO, now that that's all sorted out, I can do fun stuff in processing like this:

My very early impressions of the hardware have been good so far. The frame rates and latency of the 3d infrared camera are stunning, and the resolution of the depth sensing is way better than I was expecting. I'm really excited to start exploring the OpenNI API's to see what sort of interesting things can be done.
