Sorry. I can’t resist:
Todayâ€™s Zunes claim to uniquely provide wireless sync, but they require being plugged in order to do this! That means Microsoftâ€™s wireless sync has as many wires as Appleâ€™s USB sync, itâ€™s just 20 times slower. Thatâ€™s not an advantage nor a feature. Itâ€™s a marketing lie.
According to this informative article, this is one of the reasons why the Microsoft Zune is still failing compared to the Apple iPod.
