Strangely, in my little world, I'm seeing a surprising uptake in WIndows Phones lately. Never thought I'd see it coming. It seems people who have been happy with Android are wanting a little more, and are horribly confused by the iPhone's single button interface, and see that Windows Phone 8.1 is easier to figure out than the latest/greatest version of Android.
Just my little ecosystem, correlation does not equal causation, but I'm finding it fascinating. Microsoft might still have some life in it. (Helps that Cricket is now giving away a couple different free Windows phones)
