Some aspects of the Xbox 360 have changed since its launch in 2005, such as the addition of an HDMI port, built-in Wi-Fi, support for 1080p, and two total redesigns of the system—the Slim system and later the "E"—but the core of the hardware hasn't changed much. It's impressive that an initially underpowered system (compared to its main competitor the PS3) pumped out good-looking games and had an impact on the industry with its emphasis on digital media distribution and online gameplay.
