Overall i found it disappointing
Good: The mpeg4 playback was good & I didn't have to convert to wmp. It sounds good as the above comments mentioned
Bad: The 'squirting' feature only works on about half of the songs available on the zune marketplace, at least that's what I've found. The zune points system just as the xbox 360 system is a joke. It's too big... I also just heard about MS paying Warner Brothers per Zune sold!? WTF?
I bought it to replace an aging iPod but regret it now. The limitations exceed its usefulness.
