In addition to its position that Android will continue to dominate the global smartphone market moving forward, Gartner on Thursday revealed its projections for Microsoft’s Windows Phone platform. According to the firm, Nokia’s strong global position will drive Windows Phone adoption at an impressive pace, capturing 5.6% of smartphone unit sales in 2011. Gartner goes on to state that sales of devices featuring Microsoft’s mobile OS will surpass RIM’s BlackBerry OS in 2013, and will then move past iOS in 2015 to account for 19.5% of smartphones sold globally, compared to iOS’ 17.2%. Gartner’s determination further supports the notion that Nokia will drive global Windows Phone sales rapidly, as proposed by several other firms including Ovum and IDC.
