Pages on my iphone

I love using the Pages application on my iPhone.  Lately I've been using it to start preparing for my Christmas shopping.  I typed a Christmas list using my iPad first and when I pulled up Pages on my iphone it had synced the information to my phone over the cloud automatically.  I hear people say how you can do these same things on a droid phone but iphones make it where you don't have to be a tech genius to figure out how to do it.
