An Xbox is an Xbox, it still has the same stuff inside. I think it's ridiculous to buy a "limited edition" Xbox when the regular ones are so much cheaper.
Its not any cheaper to buy the regular Xbox($149.99) and Halo($19.99). You get he limited edition green Xbox and Halo for the same price $169.99, well a penny more. If you want an Xbox and don't have Halo then why not get this instead of the original, be different.
