Looking at buying an iPad2 for my mom as a e-book reader and probably using a few apps. She'll figure out that part of it. Plan is for me to download the books via my wi-fi here at the house to the iPad and then take it to her in the Assisted Living facility...They don't have wi-fi... When downloading the books, do they truly download (the whole book) or are they just read online? Do most apps work without a wi-fi connection? or is it like my iPhone where you need either wi-fi or 3G for updating content for the iPad?
