Eric Ligman, from Microsoft, posted a great blog post this week listing all of the SharePoint 2010 Virtual Labs that are available from Microsoft. His blog entry is here: http://blogs.msdn.com/b/mssmallbiz/archive/2012/03/13/sharepoint-server-2010-msdn-virtual-labs-available-to-you-online-plus-more-sharepoint-2010-resources.aspx
