How much do you know about BI in OpenOffice? How about LibreOffice? First, glad to hear you weren't injured by the quake.
Second, future is uncertain for OpenOffice, so I'm not sure why you'd be asking that.
LibreOffice has some nice features - but loses hands-down as an BI client against Excel. I dare say that few (if anyone) using Excel for OLAP access, PowerPivot functionality, or Excel Services would be happy with LibreOffice.
I would have thought you'd love the VertiPaq in-memory engine :)
Need to remember something - last May, SQL Server 2008R2, SharePoint 2010, PerformancePoint Services 2010, and PowerPivot/Excel 2010 all RTMd at the same time. The MS BI stack, which was (with some justification) previously called a Frankensuite because of fragile integration points, became tighter. Still not perfect, but much better.
People can complain about licensing - but MS is a much bigger player in corporate BI.
