You don't have to but if you do you get to chat, play, and download a lot games.
I don't understand your question. Which Xbox 360 you use has nothing to do about Xbox LIVE. The only thing that matters for Xbox LIVE is your internet connection.
No. (360)
Yes, you are not required to have or use an MSN account in order to use an Xbox 360, either offline or using Xbox LIVE.
no but xbox live will work on xbox 360 live you said that rong you mean xbox live works on the x box 360
You can use the xbox 360 still but the adapter or an Ethernet cable enables you to get xbox live and play online
As long as you have an internet connection, you can get xbox live on a 360 or a slim.
Yes,Beacuase Its STILL xbox live
You can not. Live is for the Xbox 360 and only the Xbox 360
yes I've got an arcade and xbox live works fine
No, original Xbox controllers do not work with the Xbox 360, so any games you download from Xbox Live Marketplace will use the Xbox 360 controller.
You would have to recover your gamertag onto your xbox 360 console again.
