Windows Phone is a burning platform at this point, Microsoft canned most of the people working on it and left a few dozen interns working on it, hence why the Windows 10 images for the Lumia as of late have been very unstable.
I mean, if I could just get a nice Maemo Phone I'd be happy, like throw that on a Lumia 920 and I'd be content. There is definitely room for innovation in the mobile space, and both MS and Nokia have the hardware side of it down, they just need to choose a platform that people can get behind and make it easy to move to it (eg. have a preinstalled app compatibility layer).
Sadly, its time to migrate off Windows Phone.
