Right now my wife and I have two computers (one is gone but we forgot to deauthorize it even though we wiped the hard drive) attached to our iTunes account. Basically just my desktop. We have three devices attached so far: iPad x2 and an iPod Nano. My entire iTunes library for Photos, Videos, Music, and more is located on a 1TB external hard drive. I am thinking about going back to Afghanistan for a year. If I were to do so, I would buy a cheap Windows laptop and load iTunes on that laptop (that would be the third device) and my wife would put it on her laptop (fourth device). What would I need to do in terms of backing stuff/porting stuff over from my desktop to take with me? Would I just clone my 1TB external drive for both of us, install iTunes on both laptops, and take it overseas? Or would I need to back something up and put it on those laptops in ADDITION to iTunes? Sorry if this is as confusing for you as it is for me.
