Office 2013, especially the preview version of Office Home & Student 2013 RT that comes with the Microsoft Surface tablet, changes the model for writing add-on programs. There are now Office apps and an Office app section in the Windows Store. Many of these apps are free, but it's easy to see enterprise-oriented apps being developed and charged for. Microsoft's implementation of the apps in Office 2013 is clumsy in some ways, but promising.
Microsoft Surface with Windows RT, the version of Windows 8 for ARM-based tablets, ships with Microsoft Office Home & Student 2013 RT. Among the features missing, when compared to previous Office versions as well as Office 2013 for x86/x64 processors, are macros, add-ins, and content that requires ActiveX (Microsoft ActiveX and Silverlight are not supported in Windows RT).
But Microsoft made up for these deficiencies in part by introducing an app model for Office that adds capabilities to the various Office programs. You can make your own apps -- basically webpages that are hosted inside an Office client application -- or buy them in the Office App Store. I tried one of these new apps for Office 2013 on my Surface tablet and saw that it actually worked. I'll step you through the Office app installation process and try to give you an idea of how one app works in the new Office 2013 world view.
