The Xbox 360 is one of the most powerful current generation consoles available. Having been out for over a year, the 360 has a great selection of games. I've only owned it for 2 months now and I've already purchased 5 games and there are still more I want for it and TONS are coming out during the holiday season.
The greatist thing about the Xbox 360 and what it has over the other consoles is Xbox Live. Its never been so easy to connect with friends and duke it out for bragging rights all accross the world. Not to mention the included headset is a great communication tool.
One weakness with the console is a lack of Wifi. It would have been very cheap to include a wireless module and alot easier for people to connect to the web with it.
Included with the system is a Wireless Controller, AV cables, 20gb harddrive, and a Headset. The wireless controller is one of the most comfortable controllers out there. Overall I feel the 360 is the best current generation console and I highly recommend it.
