Current price: $199-$399, depending on the configuration
Five years later, the sleeker, quieter Xbox 360 Slim is smaller, has built-in Wi-Fi and HDMI, and comes with a comparatively beefy 250GB hard drive--more than 10 times the capacity of the original model.
Besides hardware and cosmetics, the Xbox 360 has undergone multiple OS and interface changes under the hood, too, adding Nintendo-like avatars, streaming services like Netflix and Hulu Plus, and compatibility with Microsoft's Zune store.
Most importantly, the motorized Kinect camera peripheral adds motion controls and voice commands to a unique library of games. Bundled in, the $399 Kinect Xbox 360 package costs exactly what the first console did.
Yes, the Xbox 360 still looks like a tower PC (now, a little more like Alienware), but its hardware is definitely improved. Its software and interface, compared with the 2005 version, are nearly unrecognizable. Just like in 2005, the Xbox 360 still doesn't come packaged with a game, a Blu-ray drive, or a second controller, but it's certainly a much better value than its original incarnation.
