iCloud

With iCloud,when you buy a song on one device,it instantly downloads to all your others.take a picture/snap here;it shows up there. Start a project in one place,and pick up right where you left off in another. Capture the moment here,and it's waiting for you there.Make a change on this,and it updates on that.And with iCloud,it all works automatically and wirelessly. So you always have the things (which) you want exactly where you want them.
