Pyramid Research has calculated that the smartphone market will increase from 16% of global handset sales this year to 37% of the market in 2014. It says emerging markets will account for most of the sales; although the USA is currently the world's leading country for smartphone sales, this leadership will switch to China in 2010. Brazil, India, Turkey, and Nigeria will be the fastest-growing markets over the next five years, with Latin America becoming the fastest-growing region. [Press release]
