I just bought my wife a new 8GB Nano to replace her 4 year old 4GB Nano. How do we get all the files off the old Nano and onto the new one? I believe there are more files in her iTunes than will fit on her old 4GB Nano, so there's probably some files on the PC that would need to be added to the new Nano. Secondly, once her new Nano is all set up, how do I go about making the old Nano my own? What I mean is, how do I delete her songs from it (our music tastes are much different for the most part) and then add my songs? Once I start buying music or ripping my CDs, will all of our songs get thrown into the same iTunes library or can I create a separate iTunes on our PC? Thanks.
