Xbox 360 Reviews..
The good: All games for the Xbox 360 are in high-definition, as is the excellent, user-friendly Dashboard interface. There’s built-in support for wireless controllers and excellent online gaming, content down loads, and communications via Xbox Live.

The console is not only backward compatible with many (but not all) original Xbox titles, but it also doubles as a superior digital media hub and Windows Media extender. The system’s online Marketplace allows easy purchases of mini-games, movies, and TV shows.
