Chapter 6. Syncing Your Contents with iCloud
Besides purchased content, e-mails, contacts, and calendars, iCloud also stores your other documents such as text documents, spreadsheets, and presentations. Unlike other services, iCloud also syncs your documents. It's really useful if you work on multiple devices. You don't need to transfer the files from one device to another. Just let iCloud do the synchronization bit, and you get the most recent files on any device. This feature is known as Documents in the Cloud.
