Emerging markets are becoming a hotbed for smartphone sales with 64.8% of all smartphones shipped in 2013 headed to a destination that one would call an emerging market, That is up from 43.1% in 2010. The average selling price of a smartphone will drop to $372 USD in 2013 from the $407 price tag in 2012 and the $448 USD average price from 2011. By 2017, IDC sees the averge smartphone price down to $309. And while this is obviously good news for consumers, it isn't great news for phone manufacturers and component suppliers. Both will have to drop prices and overhead in order to compete and profit in an environment where the end product is dropping in price.
Vendors are keeping prices down by offering 3G only models. This enables the manufacturers to buy lower priced components like 3G radios providing buyers with a "good enough" experience that gives them reasonable data speeds at a low price. Overall demand for smartphones is coming from strong buying from consumers who have a wide number of models available at different price points to choose from. For many users, the smartphone is their main computing tool.
