I used to own an ipod, I now own one of the big 30gb zunes..

Honestly, itunes/ipod and zunemarketplace/zune are the same in the userfriendly area, they both work the exact same way...

Zunes have wifi. something IPods dont..

I also have not played with the new zunes yet, but they have the flick pad (Kind of like how the ipod's used, just you flick up and down like a scrollbar)

I would honestly, consider them pretty equal, just the Zune is longer in height...

I'd go for the zune, just to get out of the ipod hype:P
