What's missing in Gartners latest BI MQ?

I haven't seen the full text yet but did get hold of the MQ image from this Oracle blog that also contains some interesting observations and snippets from the full text. What you don't see however in this blog is the movement and reshuffling that took place between the 2009 and 2010 editions of the BI MQ, so here they are for comparison: (copyright Gartner Group)

So IBM and Oracle switched positions, Microsoft is moving into the BI Gorrilla space and SAP is suddenly more of a visionary than SAS (they are?). Actually, this is one of the first MQ's where SAS is not on the far right of the quadrant but loses this position to IBM. Must have been caused by the SPSS acquisition, but buying another tool doesn't mean it's automagically integrated.... Other intersting movements are made by QlikTech and especially Spotfire who both migrate from the Visionaries to the Challengers. And there are a couple of new entrants too: both Targit (Danish BI vendor) and Tableau made it to the MQ, the latter even right into the Challenger quadrant which is rare (most vendors start in the Niche quadrant). What's also interesting is the fact that all three challengers offer a somewhat similar class of highly interactive, visual analysis tools.

However, the most interesting (and for some: annoying) observation about the 2010 BI MQ is that none of the Open Source BI vendors were included! Probably again because they failed to meet the revenue criterium, which undoubtedly will cause much discussion about the inclusion criteria (again). Revenues aside, the biggest BI survey (the one by Nigel Pendse) looks at real adoption and usage and only sees a handful of responses mentioning SpagoBI, Palo, Pentaho or Jaspersoft. Maybe the adoption of these tools isn't so widespread as the OS BI vendors want us to believe?
