Apple’s iOS – on iPad only! – passes Linux in U.S. operating system use – MacDailyNews - Welcome Home: Pingdom reports, “Not only is iPad now so widely used that it shows up in this list, iOS for iPad has managed to pass Linux as a ‘desktop OS’ (we use quotes, because tablets will probably soon make up their own category). In fact, it passed Linux sometime around December. Not bad for a device that was launched just back in April of 2010.”
