Let's assume you make a business case before investing in new technology. (You do that, right?) How are you going to do that for Office 2013? Cloud or mobility might make that case for some; new and improved features also might play a role in justifying the cost and effort. The new release adds touch and stylus support, for instance, although you'll probably need to be a Windows 8 shop to make the most of that upgrade. Office 2013 also features Skype integration, especially with Lync. Want to edit a PDF inside Word? You can do that now, too. Those are just a handful of examples. Microsoft's TechNet site offers a full breakdown of what's new in Office 2013 for IT pros.
