Hey guys, thinking about buying an Xbox 360 next week and I found one for $265 new. It is the "XBOX 360 ARCADE EDITION". What is the difference between this and other 360's?? It can still run all 360 games can't it?
Tell me about the hard drive. How necessary is it? What is it used for? The arcade edition doesn't have one so I am wondering how necessary it really is. Can you buy an external one for it?
