Kinect makes YOU the controller. With a dedicated, specialized port, the Xbox 360 250GB is built to connect seamlessly with the Kinect sensor and have you up off the couch and into the world of Kinect in no time.

In addition to its revised aesthetics, the Xbox 360 E also has one fewer USB port, no AV connector (and thus is HDMI-only), and no longer supports S/PDIF.
