Microsoft Office Web Apps are online companions to Microsoft Word, Excel, PowerPoint, and OneNote, enabling people to access and do light editing or sharing of Office documents from virtually anywhere. Office Web Apps is available to consumers and businesses through:
- SkyDrive in Windows Live: For consumers and small business users, Office Web Apps is available on Windows Live as a free service through SkyDrive offering
- On-premises using SharePoint 2010: Business customers licensed for Microsoft Office 2010 through a Volume Licensing program can run Office Web Apps on a server running Microsoft SharePoint Foundation 2010 or Microsoft SharePoint Server 2010.
To understand the user experience and features in both cases, you can refer to Using Office Web Apps in Windows Live and Using Office Web Apps in SharePoint pages in the Office 2010 product information and support website.
If you want to experience Office Web Apps features but do not have enough infrastructure, you can log on to SkyDrive and try it out there for free. Just upload a document in the SkyDrive or try creating a new one. You should get a prompt for activating Office Web Apps for your account if not already enabled.
From Office 2010, you can also save a document directly to the SkyDrive. So, no need to save the file to your computer first.
Only thing to keep in mind is that not all Web Apps scenarios are currently available in SkyDrive. For example, you cannot create/edit Word documents. You would get a “Still to come…” message on the screen in such cases.
