The main reason I would want to get a Windows Phone is for the camera. Nokia still seems to be the closest one gets to getting a reasonable point and shoot camera in a smartphone.
I started with a blackberry, then moved to iPhone 4S. Bought a MacBook Air, Mac Mini, iPad and now I am using a Nexus 4 for my main phone. My main workstation is Windows 8.1. Note that I rooted both the iPhone 4S and Nexus.
At this point, the camera is not enough of a reason to switch over. I'm over the app love I used to have with the iPhone ("wow, all the cool apps!!") so the lack of apps doesn't mean much. I'm just platformed out. The thought of switching to yet another platform and going through all the hassle isn't worth it anymore.
I love the camera on my 920, it takes great pictures (for a phone), and I have been wholly satisfied with WP as an OS. I have missed the integration with Gmail etc on Android. That's been the worst of it, and it has been manageable.
Given up on any phone cameras. Missed so many opportunities and moments due to camera lag and shitty software. I drag a proper DSLR around with me now most of the time.
If you apply thought and patience rather than treat it like a quick draw weapon, the results are better. For example, just a tree I walked past in London...
