Even if Apple sell OS-X as an option to PC OEMS, Microsoft will do the same thing they did to PC OEMS trying to sell Linux as an option. Microsoft don't shit their pants, they never shit their pants, they just get there giant marketshare foot and kick competition in the arse with it. And don't worry about Antitrust. Microsoft have already turned the USA into a facist state, they control all the resources. Thats the problem with capitalism, it allows the resources and hence the power to flow into the hands of anybody, hence eliminating democracy. This will not change for at least 20 years, and only if people decide to stand up. Given the arrogance of the average american in thinking their facist state is the most advanced democracy in the world, nothing is going to change soon.
