Okay, lets look.
Same: Storage Space, Price, Both play music (hopefully) and video, also can view pictures.
Zune only: Wi/Fi (not that big of a pro, I agree), FM radio, Bigger Screen, Zune Software (Not as good as iTunes, but isn't as finicky as other people have said), No Clickwheel (I still haven't gotten the hang of it), subscription service (all I can eat), Customizable background, more durable screen material, not a fingerprint magnet.
Ipod only: iTunes (big plus), lighter, tried-and-true, Clickwheel (touch sensitive can be nice sometimes), Stlightly longer battery life (I think?), can act as a portable hard-drive, Apple ingenuity and Software support, more video formats.
I'm sure I missed some stuff (on the iPod), but the Zune has a couple more pros that the Wi/Fi.
Again, please dissuade (is that a word?) me. If Jx can convince me that Creative is superior

, I will seriously consider one.
And really, lets not turn this into a battle between Microsoft and Apple.
