When you attempt to create a site using a site template, everything migrates fine, except if you have any configured web parts on the main default.aspx, they lose their settings.  Currently, summary toolbars change to full toolbars, and configured views reset back to defaults.  This causes a very large headache for me.  Also, this same situation occurs when you attempt to migrate content from say a development environment to a production environment.  Wish me luck trying to automate the process of configuring these web part after I create the site off the template, should be fun!
