Dahveed, i understand what you're saying, but you're too hung up on multi-user meaning multiple user accounts logging on to the device at startup, when that's not what anyone is asking for really, just expanded parental controls which allow some sort of control over who can access what.
Think of it this way, with an example i'm sure everyone can relate to in some way. if you're a parent and you have a cabinet with alcohol (or anything) in it you don't want your kids (or anyone) getting in to without having the key, you don't lock the kid out of the house in its entirety, you just lock the cabinet with the alcohol in it and only give keys to those who should have access.
Also, i don't recall any iPad commercials or advertisements warning you should have no expectation of privacy with the device ;-)
the iPad is great for families, but parental controls are definitely not new technology, and they are already partially included via the form of restrictions. I'm just looking for them to be expanded upon, at least to those programs already included with the iPad by default.
