Apple's iTunes products are on track to contribute approximately $13 billion to the company's revenue by 2013, according to Global Equities Research analyst Trip Chowdhry. Although Amazon's Kindle platform may have an edge against iBooks in the current market, the analyst suggests many publishers are beginning to favor ePub format, used by Apple, rather than the Kindle format. The iPad is also said to be the preferred e-book reader among students.
