Linux share of netbooks increasing

I just read this Computerworld article that says the Linux worldwide netbook market share is increasing, and currently stands at 32% of the worldwide market, while Windows runs 68% of the netbook computers internationally.

To me this is very, very interesting, because it appears that Linux may be installed on as few as 4% of netbooks in the U.S. market. Really, this amazes me to see such a disparity between netbook sales in the U.S. verses those international sales numbers. In short, internationally people seem to be embracing Linux on the desktop with no concerns. Why is it so different in the United States?

I feel a trip to Best Buy coming on, lol.
