Microsoft Smart Solutions article on SharePoint "Microsoft's SharePoint products and technologies are central to the company's 2003 product cycle. They form the collaboration foundation for Office 2003 and also represent the first major .NET Framework-based Microsoft server offering above the Windows platform layer. The new Windows SharePoint Services (WSS) technology included with Windows Server 2003 for personal and workgroup-level collaborations, along with its sibling Microsoft Office SharePoint Portal Server 2003 (OSPS 2003) for enterprise portals, together represent a significant milestone in the ongoing delivery of Microsoft's .NET strategy."
FYI -- my view on SharePoint's role in Microsoft's collaboration strategy.
