I have been playing with a Nokia Lumia 521 for a few weeks and really like it. I would love to make it my primary phone. However, there is one feature that Windows Phone does not have that is a deal-breaker for me. As a big listener of audiobooks and podcasts, it is essential to be able to listen at 1.5x or 2x pitch-corrected speed. The weird thing is that it was possible for third-party developers to do this in Windows Mobile (Core Player, for example, did this very well). Of course, Android and iOS have had this capability for a long time. Any hope that Microsoft will ever add this feature? It doesn't seem like it would be that difficult to implement!
