:The iPod isn't supported because the King Of DRM Steve Jobs wont licence Fairplay DRM to any other content service provider ,even though Walmart sells millions of iPods for him .
If anything you should complain to Apple about their DRM not being interoperable outside the iTunes\iPod ecosystem .
I think the reason for Apple forcing this is to keep the iTunes system running simple and the way it should. Take a look at the Zune system (how the Fairplay DRM does not work with other Media Player approved DRM) to see how this can get to be a PITA for Joe Consumer.
