It's only Tuesday and there have been two more acquisitions in the open source market. While these aren't huge deals on the scale of JBoss or MySQL, they do signify ongoing consolidation in the market.

-Nokia acquires Trolltech
-SpringSource acquires Covalent

Both these acquisitions seem to make sense from a perspective of customers, users, and the companies on both sides. It's also interesting that these two recent deals show both the adoption of open source technology by a non-open source company and the combination of two open source companies to build a larger open source entity.
