Xbox 360 S

Two major revisions of the Xbox 360 were released following the initial launch. The Xbox 360 S (typically considered as "Slim"), launched in 2010, featured the same core hardware but with a redesigned, slimmer form factor with a smaller-sized 250 GB hard drive. It also added integrated 802.11 b/g/n Wi-Fi, TOSLINK S/PDIF optical audio output, five USB 2.0 ports (compared to the three from older versions) and special port designed for the Kinect peripheral. The Xbox 360 S replaced the base Xbox 360 unit, which was discontinued, and sold at the same price.
