Much of the announcement focused on consumer use of Office, but Microsoft announced two new versions of cloud-based Office 365 services for businesses.

Office 365 ProPlus is for enterprises and includes cloud-based management of the application suite and unspecified advanced capabilities. Office 365 Small Business Premium includes business-grade email, shared calendars and high-def Web conferencing and is aimed at smaller businesses.

Demonstrations at the press conference included use of an 80-inch touchscreen to conduct an HD videoconference. The screen was made by Perceptive Pixel, a company Microsoft last week.

The company envisions use of 80-inch touch displays as a means of conferencing that draws in HD video of participants and blends it with documents, slides and whiteboards on which members can draw with styluses.

In developing Office 2013, Microsoft spent a lot of time getting the applications to interoperate with each other to enhance collaboration. So during a demonstration today, Microsoft showed OneNote interoperating with a Lync conference by automatically creating a notebook for the meeting where participants could find the agenda, the list of who attended, a log of what they did and what resources such as PowerPoint presentations and Word documents they viewed.
