Late last week, BGR wrote about a recent report suggesting Microsoft’s share of the global smartphone market would overtake Google’s share in 2015, and Windows Phone would become the best-selling smartphone platform in the world at that point. On Tuesday, the Pyramid Research analyst responsible for the report published a follow up explaining that her findings were misinterpreted. Pyramid’s Senior Analyst Stela Bokun explains that Windows Phone is poised to overtake Android’s massive market share much earlier than that — as soon as 2013, in fact. Beginning this year, Bokun sees Windows Phone popularity exploding even faster than Android adoption has since its introduction in 2008. The analyst attributes the coming Windows Phone boom to Microsoft’s partnership with Nokia; the Finnish cell phone giant is set to bring the end user cost of Windows Phones down, thus accelerating adoption dramatically. Bokun also notes that other manufacturers will continue to support Windows Phone, which will help make the devices widely accessible. “With the change in the price of WP devices, and the multivendor strategic approach of Microsoft, the main advantage of Android – scale – may be removed,” she wrote on Pyramid Research’s blog on Tuesday. It certainly seems like a long shot, but Pyramid Research forecasts smartphone sales individually in 51 separate markets, and the firm stands by its findings. We also shouldn’t forget that it only took Google 2.5 years to get its Android OS where it is today, so it’s quite clear that anything can happen.
