As the high-profile underdog alternative to Apple's iPod portable media player, the Zune has endured an unfair share of jokes and scorn. Proving the adage that "what doesn't kill you, makes you stronger," Microsoft has taken four years'-worth of hard knocks and forged the Zune HD. As one of the only iPod alternatives that can match the iPod Touch in beauty and pricing, the 16GB ($199), 32GB ($269), and 64GB ($349) Zune HD also includes a unique stable of features worthy of Apple's envy.
