Acer's smartphone strategy is currently focused solely on making Android smartphones but that may change if Windows Phone reaches 15% market share in Europe. The company's VP of Smartphones Allen Burnes said in an interview that Acer wants to see more demand from consumers on WP before they take risks with Microsoft's OS.
The Acer Allegro is the only WP smartphone the company has made so far. Now, almost three years from its launch, the company still hasn't made a second one, but that may change sooner than you think.
Not everyone shares Acer's vision on Windows Phone, though. Sony has been rumored to be currently in talks with Microsoft to make a Windows Phone under the Vaio brand. An official photo of an upcoming Samsung WP has also leaked just yesterday.
