Xbox 360 slim 4GB with Kinect $200. That's ~$200 off the retail price for the console and Kinect separately, $100 off the usual price of the bundle. Great deal, especially if you're someone who doesn't expect to store media or download playable content onto the box. Of course, there are ways to expand on that 4GB memory (you can get a 16GB USB expansion, an official 250Gb or 320Gb Xbox drive, or if you've got enough tech savy modify an off-the-shelf 250Gb or 320Gb drive for much cheaper).
That's a seriously unbeatable deal if you want in on the Kinect.
