Hi, I hope someone can explain this to me. What I understand is that only the photo app will have photo stream service for last 1000 pics for 30days. All other apps books etc will have to be downloaded, so icloud is not going to be a streaming service. Since I have a 16GB ipad2, I was hoping with icloud I can have additional space, but it doesn't look like it or maybe I did not get the point. Can someone explain how it all will work.
