SharePoint Products and Technologies provide enterprise-scale capabilities to meet business-critical needs such as managing content and business processes, simplifying how people find and share information across boundaries, and helping to enable more informed decision-making. Using the combined collaboration features of Windows SharePoint Services and Office SharePoint Server 2007, plus the design and customization capabilities of Office SharePoint Designer 2007, organizations can enable their users to create, manage, and more easily build their own SharePoint sites, and make these sites more discoverable throughout the organization.
Office SharePoint Server 2007 offers enhanced features and additional features that are unavailable on a Windows SharePoint Services site.

However, Office SharePoint Server 2007 includes many additional site templates (Fantastic 40, codeplex) related to enterprise and publishing scenarios.
