In 2009, Apple sold more iPhones than it did in 2007 and 2008
combined. In 2010, Apple sold more iPhones than it did in 2007,
2008, and 2009 combined. Last year, Apple sold 93.1 million
iPhones, slightly more than it did in in 2007, 2008, 2009, and
2010 combined. The pattern continued.
Imagine if that holds true for 2012 as well.
Richman also makes a strong case that Apple sold more iOS devices than all Android devices combined last quarter.
