When you are online and signed in, the new Office saves your documents to the cloud (Microsoft SkyDrive) by default. You can get them on your tablet, PC and phone and share them with others by just sending a link. All of your Office applications, documents and personal settings go where you go. That means things like your custom dictionary follow you no matter what device you're using. Plus, when it's in the cloud, it's backed up—you don't have to worry about losing your work.
