I need to be president.
I'd declare myself Emperor Jimmy the 1st of the United Empire of America. I'd make MS illegal, have gates undergo genital and cranial amputations, and make open source the official state-endorsed software license. current commercial software would get grandfathered in. Windoze would however be outlawed.
I think lindows would be illegal too, that way Lycoris can become the dominant "windows replacement linux".
my foreign policy would be really cool too. By tearing down the pigopoly, I'd do everything I could to improve the image of america to the rest of the world. I'd try to make peace with the muslims rather than trying to exterminate them the way asshat bush wants.
