Content Aware is not new to Photoshop CS, but its has been taken places in Photoshop CS 6. Earlier a selection had to be made (it still has to be) then quite some other things had to be done for content Aware to work. In Photoshop CS 6 it is much more simpler. You just make the selection and move it where you want it and Photoshop does the rest.
