Okay, so here's what is going on: My boss's wife's iPad (you've got to like where this is going) was originally synced to her windows laptop. He then synced it to his macbook. She now has a new laptop and wants to sync it back to her own material. How can we do this without having all the data on the ipad erased? I'm not sure what my boss has done but this is what his wife wants (so she doesn't lose any apps/calendars/etc).
