What can I use the iCloud for if I have a mac and an iPhone? I look for a method to secure and protect some of important data in my phone (contacts etc) and some documents and photos in my mac. But it seems iCloud isn't gonna help me in that. Synchronizing documents between the mac and iPhone seems to be useless for me. I only like the ability to store contacts online and synchronizing them. What would you use iCloud for if you have the same two devices as mine?
