Love it or hate it, Apple had a pretty stellar 2011. According to crunched numbers from Asymco, between its iPhone, iPad and iPod touch, the Cupertino outfit sold some 156 million iOS devices in 2011, marking a grand total of 316 million in the mobile OS' short history. What's most interesting here, however, is the fact that last year's digits alone have completely blown past the 122 million units daddy Mac has managed in its 28 years of existence. It's no wonder the company borrowed a few tricks from iOS for its latest desktop operating system.
