This is probably a stupid question, but here goes anyway. I know that you can set up separate accounts on a computer, and one person cannot see the other's files, etc. Is that possible with an iPad? If my husband also uses my iPad with his own iTunes account, will he also be able to access my apps? Can he have different settings, different photo libraries, etc? Or is everything all lumped together, and you just have to separate apps by putting them on separate pages? Thanks!
