I've been thinking about this lately. What is the current state of the platform? Microsoft appears to be intent on providing services and software on iOS and Android, thus reducing advantages of the the windows phone. They also have been focusing on rolling out low end phones with some success, but at the risk of cheapening the brand. Some major developers have dropped them or refuse to produce their apps for the platform. Nadella seems less inclined to grow the phone Rumors of the platform may run Android and/or be dual boot While marketshare in Europe appears to be better, the picture is not rosy. I picked up a used Lumia on swappa, partly for my kids and partly to play with windows 10. I like the phones, the UI and what the OS brings. I think if the rumors are true about the running Android or worse dual booting, that will only hasten the death spiral. Why should developers create windows programs when it can run Android apps? Odd coincidence, Microsoft used this argument to marginalize OS/2 over windows back in the day and now they're potentially falling into the same trap.
