Since I use a lot of Microsoft enterprise tools, including BI stuff like OLAP and Reporting Services, this link on Dr. Dobbs was interesting to me.  http://ddj.com/dept/database/188702217?cid=RSSfeed_DDJ_DataBase discusses PerformancePoint Server 2007.  The next Generation BI stuff from MS is apparently going to move Excel as the centerpiece of the user experience, is what I get out this article.  That's a good thing for involving more users in the BI space, IMO.  I know I'd love to see more robust OLAP tools for Excel.
