Until now, the USA has been the power in IT. They bought the most of everything so they could tell the OEMs what to make. July, 2011 changed that. China bought more PCs than USA.
It’s possible this is just a temporary “blip” because the US economy is slumping but the whole world of PCs is changing. This may well be a tipping point where the country that produces most of the PCs and that consumes most of the PCs and that does prefer GNU/Linux calls the tune. According to Canonical they have 100% annual growth rate in China and Lenovo alone was shipping a million units.
