HEre's a snip:
Aside from the Microsoft fanatics and the impulsive early adopters, the Zune has failed to make any demographic shout out loud in support of the device. That's highly different from what Apple can say about the iPod, which has hordes of loyal devotees.
Part of the fanaticism with the iPod is because Apple has poured a huge amount of resources to stay on top of new content, customer service issues, and most importantly a user-friendly online store platform. Meanwhile, the Zune Marketplace confuses consumers with dollar-to-point conversions, a completely different DRM platform from MSN Music, and a difficult-to-navigate digital storefront.
