Sun says its my SQL

Suns acquisition of mysql didnt surprise me at all. Given Sun's recent flirting with Open Source movement this is a logical outcome. But what surprised me is the cost of this acquisition. A staggering 1 billion dollars. Now how could Sun gets the maximum returns out of it..? Sun might want to convert the popular "LAMP" Linux Apache Mysql Php into SAMP Solaris Apache Mysql Php. But how does it going to monetize the effort and resources its going to pump into the further development of this free database software which is not that popular in large entertprises..? Charging for support and hardware does not seem to increase the topline of Sun in the short term as far as I see. Lets wait and watch.
