I think one of the biggest things I see is the ability to handle uploads/handling of images inline of your content. You still have to provide the server side implementation (see http://paltman.com/2012/08/15/how-to-setup-upload-handler-for-redactor/ http://paltman.com/2012/08/15/how-to-setup-upload-handler-fo...) but having the ability to browse previously uploaded photos, as well as upload new ones, and have them appear inline with your content with resize handles, is pretty nice.
