Performance Dashboard for SQL 2008
Just in case you haven't seen this http://sqlblogcasts.com/blogs/thepremiers/archive/2008/06/20/sql-server-2008-performance-studio.aspx
then have a read. As I actually create dashboards and performance reporting for sql 2000 and sql 2008, and have been for many years, I'm seeing some of my work made redundant but there's other new features in 2008 I can concentrate on so it's not all bad < grin >
