i think M$ just hate the idea of OpenSource being in the market for a while, and i'm sure they'll start doing something about it,
but what i'm most sure of,( MS still don't have any solution to go with against Linux )
my company is a Microsoft distributers, and through our relation with MS, we know that they already have a Linux Phobia , lol
i know many guys lost their jobs at microsoft becouse they lost deals agianst Linux sales and solutions.
