The struggle between Apple and Google wouldn’t matter much if there wasn’t so much potential money at stake. Billions of dollars hang in the balance, and the majority of that money will come from advertising. App sales are another important component, especially for Apple. Apple has the edge in selection and quality of apps, but while sales have been brisk, developers have complained that making money is too difficult. A quarter of the 250,000 apps available in early 2010 were free, which makes no money for developers
or for Apple but it does bring consumers to the Apple marketplace where they can be sold other apps or entertainment services.
