If Microsoft would have ever gotten its #$%@ together, windows phone could have easily stolen the show of everybody out there. My entire family is on iOS except for me. Every time I pick up one of their devices my frustration level goes through the roof. The OS needs a major refresh.
I have a Windows Phone, and the app gap is annoying and I will probably have to switch to Android soon, but the user experience is simply amazing otherwise.

Drag and drop of files (any type, not just photos and music). But....MS gave up on it
