Ok I need set up help. I have an iPad and now the kids will be getting their iPads for Christmas. What is the best way to have three iPads working on one computer? I want them to have their own music and apps and I don't want to pay twice for an app they might both want. There are a few apps they will both want to play but I'm unsure if data will be transferred between the two. iCloud confuses me.. Do I set them up individually or transfer data from iTunes?
