Hello! I'm new here, and this is my very 1st post. I read MacRumors practically daily, and I was looking the answer for a question. I don't know if you can answer it, but I hope that yes. Here's the question: is there any app to allow two people to use the iPad at the same time??? It's for my son, that wants an iPad for him, but I think one it's enough. Please help me!
