Give your xbox tlc and it is more reliable
Trust me, take proper care of it, ie give it vent space and xbox will last for nearly 6 years like mine did. I got it as soon as it came out and have only had one fault which was fixed immediately. I am only getting a replacement as the fans are not what they used to be. Compared to my ps3, I think that xbox live is much more active and accessible. aswell as a nice controller which fits into your hands. Really, the graphics (unless watching a blu ray) are the same as a ps3, and with games like gears and halo, and getting dlc earlier than s3 it makes a much better console.
