I don't know why people assume Americans love Microsoft.

Even if you don't like Microsoft, the fact that buying a domestic product helps the economy and hence helps yourself is in the back of people's heads and thus is a partial reason why XBox is so popular in America.  The same can be said to every other country in the world, some to more extent than others however.
