Is it really failing? It's a latecomer, but it's gaining traction. Windows Phone phones are best sellers on AT&T in the US, and supposedly beating the iPhone in terms of sales in China. With Windows 8 coming out, who knows what will happen. Speculating on whether it's going to fail or not at this point is just that -- heavy speculation. The fact that the Windows Phone is a very decent OS, is simple to use, has a decent app market, and is being promoted on so many fronts (including the main service providers, because they benefit from a 3rd smartphone provider), all makes me believe that it is bound to be a success if they continue to improve the foundation that they have and don't make big mistakes.
