Dallas – The number of global smartphone users is expected to reach over 2 billion people by 2015, when unit sales will exceed 800 million, according to a report from market research firm Parks Associates.

Unit sales are projected to grow over 175% from 2010, driven by hardware and software innovations like video chat and app-enabled content consumption.

The report notes that the most successful manufacturers — including Apple, HTC and Samsung — have also been the most innovative, while companies slow to innovate — which the firm said include Nokia and RIM — have suffered declining market share.

“Smartphones represent a new lifestyle,” said Parks Associates’ Harry Wang.

“Consumer desire for that lifestyle has accelerated the traditional mobile phone replacement cycle and will drive near-term hypergrowth of the smartphone market.”
