Time Machine now allows you to select more than one hard drive to save backups. Amongst other things, Messages offers unlimited free iMessages, video conferencing with Facetime and photo/file sending. Lion users can try the beta version of Messages which is the same as iMessage on iOS but the final stable version only works on Mountain Lion. It integrates the address bar and search box including Google searches, favorites and history. Omnibar is an added feature to Google Chrome in Mountain Lion. Password Tabs allows you to see passwords saved in Safari.
Facebook sharing has also been integrated into OS X Mountain Lion, as anticipated. A universal share button has been added to Safari's URL bar for reading later, add to bookmarks, e-mail, or Twitter.
