It definitely is a win that gnu/linux is the base operating system. However, IMHO, in systems of this type, the integration tools on top of the base operating system weigh more. Most of the performance gains come from how those tools are built. Not sure how many of such tools are Free Software. With gnu/linux in the bottom and a whole stack of proprietary stuff on top is not exactly a win for the community, IMHO. -- .o. I'm a Free man. I use Free Software. ..o ooo http://www.joesteeve.org/
