Why consider a Project Server 2007 deployment with Microsoft Office SharePoint Server (MOSS)?

By default Project Server 2007 gets deployed on top of WSS V3. I've listed below reasons why one should consider deploying Project Server 2007 with Microsoft Office SharePoint Server.

• Dashboards, can easily drag and drop KPI/Excel/Reporting Services webpart onto a page to create project tracking dashboard
