I am interested in getting an ipad but have several questions: -I noticed it doesn't have a USB port. Are there any items such as an adapter that would plug into the dock connector to give it a USB port? If so, would I be able to plug an item in such as an airmodem to give it 3G? I currently have an airmodem with my laptop so it would be nice if I could do the same here. -Tethering: I've heard the iphone will have tethering shortly. Would it work with the iPad? -I likely would be sharing the iPad with my wife and child. I want to be able to control which websites my son has access to and block sites such as YouTube, Facebook, and others. Can I block websites on the iPad? If so, would I be able to block these sites in a secure location so that he could not have access to it to unblock these sites? -Multiple Users: With our mac we can set up multiple users so that each of us has our own documents, applications, etc. All of us have our own iTunes accounts with some apps already for the iphone. Would we be able to have accounts for each of us when we use the ipad, to have our own apps and could these accounts be password protected? Thank you for your help with the above questions.
