See StatCounter I did a survey of the world according to StatCounter, looking for superstars. For North America, I chose Cuba although USA is doing very well. I like underdogs. For South America, I chose Uruguay, which has unleashed a whole generation of users of GNU/Linux. Africa also has Ethiopia where governments and schools have adopted GNU/Linux. For Europe there are many candidates including Spain, France, Germany and Czechoslovakia. I chose Finland because clearly something huge is happening even if it’s only one day a week… India is the GNU/Linux powerhouse of Asia, slowly but steadily increasing share and in use at the office. Oceania is the weakest continent. There are several tiny island nations using a lot of GNU/Linux but New Zealand must blow them away by users/usage. Europe is the hottest continent averaging 2.45% GNU/Linux desktop share of page-views for the month.
The bottom line is that GNU/Linux works for everyone everywhere.
