I am an Android Application Developer and I am not a Windows Phone owner. But I still believe Windows Phone will have at least 25% of market share in the smart phone sector. I think Windows Phone will success in the Enterprise Market. There are a lot of companies using Exchange Server. If Windows Phone can work better with Exchange Server better than Android and iPhone, that makes sense. Windows Phone will be the best option for a lot companies as their staff phone. Moreover, Microsoft got a strong partner network. They can use their partner network to encourage the developers to develop their apps in Windows Phone. I believe only basis on these two points, Windows Phone will success!
