Worldwide sales of smart phones are expected to reach a staggering 1.1BN in 2015, according to a recent report by Gartner. As early as the end of 2011 it is expected that smartphone sales will be 468 Million units, a 57.7% increase on last year. This growth should continue over the medium term culminating in 1.1 billion units expected to be sold in 2015.
Business Insider says global app downloads for year-end 2011 are expected to balloon to 29 billion, compared to only nine billion in 2010. Such stellar increases are largely due to the proliferation of smartphones around the world. The total smartphone install base is expected to grow 46% in 2011.
