The main new thing I've seen that 2013 offers is improved support for tablets/touch screens, not surprising considering all the effort MS has put into its Surface Tablets. We don't have anything aproaching universal tablet use at my office, but it is a useful improvement, more so as people continue to expand their tablet use to more of an actual work device and less of a notepad/entertainment device and as convertable laptop/tablets gain traction. Otherwise, I would consider Office 2013 to be a forward looking refinement of 2010, and not nearly as significant of a revision as 2007.
