That is cool. At the rate we adopt new technology though, I won't use 2008 until 2010. We just upgraded to 2005 two weeks ago. The upgrade to 2008 is very different from the upgrade from 2000 to 2005.
SSRS has been completely rewritten. SQL 2008 has also been revamped to use resources more efficiently. They haven't added as many new T-SQL constructs, but the ones they've done are pretty cool. You can also essentially place multiple GROUP BYs (e.g. grouping sets) in a single result set.
