Hierarchical work items in VSTS "Rosario"

If you didn't know already, the Visual Studio Team System "Rosario" bits are available for download (including a VPC image).  One of the major features many of my ISV partners have been waiting for is the hierarchical work items.   Grant Holliday, a VSTS MVP has a great overview of this feature on his blog that I thought many of you would be interested in.

Also, check out Bruce's blog entry on the Free Download Manager to grab the VPC.
