The feature that I want the most is to be able to set different users account. If I pass my iPad to my brother or mom or anybody, they can access my Twitter, Facebook, photos, contacts... Same with my iPhone, whenever someone tells me they want to "play a game" on my phone, I get all nervous because they can see all my stuff. Wish apple would make some sort of Guest account or something like that. Does Android have that feature? Anybody else agrees?
