This first Zune has too many compromises and missing features to be as good a choice as the iPod for most users. The hardware feels rushed and incomplete. It is 60% larger and 17% heavier than the comparable iPod. It has much worse battery life for music than the iPod or than Microsoft claims — at least two hours less than the iPod’s, in my tests. Despite the larger screen, many album covers look worse than they do on the iPod. And you can’t share music libraries between computers like you can with iTunes.
Zune’s online store offers far fewer songs, just over two million, compared with 3.5 million for the iTunes store.
