Well I think that developers don't take windows on serious and it is their major mistake. If there were apps like snapchat and some othere apps were getting frequent support more people will move to windows. I talk to people everyday who want to move to windows because they like how clean and simple the os is but they just miss some "key" apps, if I could call them "key". So basically developers need to focus and on windows, they have to hire more people but, you know, everything is money so in the near future there will be poor support..
