2. Touch Mode

Microsoft is with Windows 8--with both traditional Intel/AMD-based architecture, as well as Windows on ARM (WOA) for ARM-based tablet hardware. One of the defining elements of tablets is the lack of a physical keyboard, and the dependence on a touchscreen interface for multi-gesture navigation.

Office 15 applications have a Touch Mode button to make the software easier to use with . According to Thurrott, Touch Mode enlarges the ribbon buttons and other controls, and spaces things out more so you can swipe and tap more accurately with your fingers.

3. Office Marketplace

You can’t develop anything these days without launching some sort of app store, and Office 15 won’t be an exception to that rule. Microsoft is planning the Office Marketplace as a resource for users to find extensions and tools to expand the capabilities of the Office software, and customize it to work the way you need it to.
