If all goes well tomorrow my household will have two iPads, each linked to a different computer with a different user and iTunes account. My question is how to manage applications and content with two iPads. For example, in a household with two iPhones, can applications be shared across the phones? if so, how? If it can, I imagine the process would be the same for iPads. Similarly, if I buy a book for my computer using my account, can my partner get the same book if authorized to use my iTunes account? I'm trying to avoid double charges for paid apps, books, movies, etc.!
