hello guys , i know lots of u here have new gaming consoles ( PS3 or x360 ) , i wanna buy the x360 , but what am concerned abt is the difference between the arcade and the elite one ... the elite comes with a 120 GB HDD ... what i wanna know is that what do i need these 120 GB for ? am sure i wont download any games from the internet for it ... so what difference would it make if i got the arcade one without the 120 GB ? 1 more thing , where will i save my progress in games ?
the price differs abt 150 $ less with the arcade ...
