The Email program lets you manage multiple email accounts, calendars, RSS feeds, contacts and newsgroups all in one place. New features include: sending up to 10GB of photos per email, instant messaging in the inbox, conversation threading and more.
You can also use the Sync feature which to automatically sync an updated folder from one computer to another when they're turned on.
Using the new remote desktop feature, you can also sync to other computers via an Internet connection, or view files on another computer from a remote device. If the computers are turned off, you can store the information online and the computers will sync when they are turned on.
