At the Microsoft SharePoint Conference 2009 at the Mandalay Bay, Las Vegas Nevada USA learning about all the new and improved functionality of SharePoint Online and using Office Sky Drive and the Office Web Applications (which are the web based versions of Excel, PowerPoint, Word, OneNote, Visio, and Access).  There is a ton of new functionality coming down the pike for BPOS and BPOS-D users.  The obvious functionality will allow you to use the Microsoft Office desktop suite in the web browser.  The great news is that most of this functionality will be available in both Internet Explorer and other browsers such as FireFox and Safari.  We already understand the set of web services available for consumption in BPOS Standard and SharePoint Online Standard.  What's coming in the next rev is an even bigger set of functionality that will allow the addition of solution files through the web browser.  Stay tuned for more from the SharePoint Conference.
