I really like my IPad, however at times i find it lacks a simple function that makes me wonder..why? There must be a strategic reason for it, or they would implement the function. An example is email level passwords. I think a lot of people would like this. It would allow you to share your IPad easily without having something private accessible. This would be great in a family setting. So, I am wondering if the reason they don't implement this and never will is that they just want people to buy more IPads? A family couldn't share an IPad, they would need to get one for the kids, husband wife etc.. What do you think?
