That little "share" icon--the square with arching arrow-- that you've seen on your iPhone and iPad, has migrated to the Mac in Mountain Lion. Pressing on the share icon in the Finder window displays a drop down menu to immediately attach a file (or contact from your address book) to an Email or iMessage (text), send to a nearby Mac using AirDrop, attach it to a Tweet, send a movie to Vimeo or a photo to Flickr. In the fall, Facebook will be added to the list to easily post photos and movies.
