But this is changing... slowly. Many teams are starting with TFS as a replacement for bug tracking (currently Product Studio) and work-item tracking (currently... a variety of systems, dependent on team). Last I heard, even Office was experimenting with TFS.

Missing from that TechSoup article is the other Dynamics CRM deployment model, CRM Online. Details here.

Minor correction to the above: Dynamics CRM Online *is* the full version of Dynamics CRM. They're the same codebase. (A few features are disabled or done differently since it's a shared environment - custom ASPXs, for instance.)
