anyone here have Kinect for Windows?

Just curious if it works well with windows 8. just wanted to know how good the voice recog, or if I can wave my hand around because my windows 8 is desktop based and it doesn't have touchscreen. I plan on using it ala minority report. The price is a bit steep right now, and Kinect 2 is probably going to come out sometime this year when the next xbox comes out, so I don't know if I should wait.
