well i already solved this problem. i'm definately doing the upgrade. i got a few zunes from woot when they were $99 - $150 and i return them to best buy for store credit of $200. overall the difference between price paid and actual price is the price of a new zune.. so i guess you can say its free
with the remainder i bought halo 3 and SKATE, and still need to get guitar hero 3 and rockband
