You bought a Mac because it's better built and has better reliability and yet you went with the Xbox, a product from M$ which is notorious for breaking down.
Stop contributing to the M$ monopoly and we can eradicate the plague that is M$ with it's unfair business tactics and abuse of monopoly.
So if you own an Xbox 360, sell it and buy the much better and much more reliable PS3. PS3 = Mac of the console world. Xbox 360 = cheap ugly PC.
