Take a Tour of Office 2010:
Microsoft Office 2010, as revealed by the just-released Technical Preview, brings a set of important if incremental improvements to the market-leading office suite.
Among them: making the Ribbon the default interface for all Office applications, adding a host of new features to individual applications such as video editing in PowerPoint and improved mail handling in Outlook and introducing a number of Office-wide productivity enhancers, including photo editing tools and a much-improved paste operation.
The software suite comes packed with meaningful improvements, but the most striking addition to Office 2010 is the introduction of Office Web Apps.
These are lightweight versions of Word, PowerPoint, Excel, and OneNote that are all accessible via desktop, mobile devices, and Web browsers Internet Explorer, Firefox, and Safari.

Final versions of Microsoft Office 2010 and Office Web applications are expected within the first half of 2010. Pricing is still unknown. When Office Web applications are launched, they will be free and available through Microsoft's Windows Live set of online services.
Businesses will be able to choose an Office 2010 licensing option that allows them to host their own Office Web applications.
