i wouldnt reccomend the zune 4/8, because i had bought the zune 8 two times some time ago nd both of them had hardware failures. i had calld microsoft nd they sent me a new one nd same hardware failure on the same day i had recived it.
then i went bak to bestbuy nd exchanged it for the 3G iPOD Nano.

the ipod nano is 100x much bettr. i have ownd it for 5 months so far nd havnt had any problems with it.

so i reccomend the ipod nano as its only $50 more than the zune.
and the zune program sucks
