A couple of announcements at the Microsoft Worldwide Partner Conference (WPC09) have been making a lot of noise today. One is the unveiling of the much anticipated Office Web Applications, part of the overall Office 2010 announcements – that Office 2010, SharePoint Server 2010, Visio 2010 and Project 2010 have reached the technical preview engineering milestone.

Unlike the previous online Office service offerings, such as Office Online, Office Live and Office Live Small Business; Office Web Applications are indeed browser-based Office clients. Specifically, Excel, OneNote, PowerPoint, and Word; in addition to Outlook which had the Web Access version for a number of years already.

And as part of Office 2010, Office Web Applications will be available to nearly half a billion customers at launch:

  • 400 million users on Windows Live – FREE! 
  • 90 million Office annuity customers will have access to on-premise deployments
  • Office customers will also be able to host and access the Office Web Applications through Microsoft Online Services
