I've been told that if I go from one iPhone/iPad to another (say, from iPhone 4S to 5S), I can save the old one's backup and restore it on to the new one, and get the exact same layout of icons, folders, and installed apps+settings there? Is this usually a bug-free procedure? How about keeping the apps, layouts, settings etc. in sync among selected iDevices, is something like that possible (yet)? For instance, say I have an iPad and an iPad Mini, with the same storage capacity, and would like to have the same apps and the same layout+settings on both of them -- can it be done automatically?
