All I can really suggest is that the Media Player interface on WM needs to be the Zune interface. Like Jason I had said it should be the PMP interface, but a portable interface that mirrored the desktop MCE interface was apparently to much product integration. I see the trend, as the Zune desktop interface has no relation to the Zune device interface, and none look like either the Vista MCE interface or media player on any device. Gee, maybe some consistancy would be nice. Then we can work on features and add them to everything at once, like common playlists, that sync among devices, common DRM (though I think that exists sort of). Maybe an equalizer with custom settings that sync across all the platforms.
BTW Jason, considering your admission "There was no hesitation as I immediately replied "Yes". Windows Media Player Mobile was largely abandoned at that point", would you please not suggest anything this time
Oh, and Darren, you can add Pocket Streets to your list of abandoned consumer products.
