"China has leap frogged pretty much everyone else in every aspect." How laughable. Is anyone in the world using a Chinese based OS? Is anyone outside of China really even using a Chinese OS derived from American ones? Is anyone in the US really using Chinese software? Can you name any big Chinese products or services that we use in the West besides cheap commodity stuff?
