That would be extremely relevant... if you had some facts.  A bald assertion gives very little to the discussion.  A data set (or a reference to one) would be more useful.<p>Even <i>more</i> useful would be more relevant data - like Google ad revenue from users of the Android platform, whether or not broken down by country, and whether or not correlated against average income from that country.  Anything else is just speculation, no matter how firmly claimed to be fact.
