The Long Tail: Friday Fanboy: the Zen Micro + Rhapsody To Go: "For all the genius engineering of the iPod Nano, its functionality is largely determined by the iTunes software and music service, which really leaves me cold. It may be the most popular music service, but it is far from the most fully-featured. Compared to Rhapsody, iTunes has bare-bones artist descriptions, few editorial reviews or much other useful metadata, an unhelpfully broad single-level genre hierarchy and lame recommendations. Plus the over-restrictive DRM in its AAC files makes even Microsoft's WMA look good."
