I don't think that finnish goverment would do anything, or could do even if it wanted. There is no legal basis for intervening in a such deal. Besides, they are too busy shovelling billions after billions of finnish national wealth to Greece, Ireland and Portugal in order to save German and French banks from bankruptcy if PIIGs default on their bonds. As for EU antitrust case, it might be possible. Altough Nokia's market share has plummeted and Microsoft doesn't really have any in the mobile space. I guess the EU comission could go after MS anyway. They seem to like doing that.
