My original xbox 360 developed the RROD, and in my panic when the x-clamp fix didn't fix it I purchased a new Arcade from Dell. Well, the heat gun method ended up fixing my original 360, and I didn't really feel like messing with returning the Arcade so I've decided to keep it and have 2 360's.

My question is this, to play stuff on both of them, is it easiest to just create a 2nd gamertag? My original 360 has a hacked 120gb hdd upgrade in it; can i clone it to a new 120gb and put that in the arcade?
