Well I have seen those Zunes, and they are pretty much alot like Ipods. Both play music, but Zunes can only use mp3's (I think) But music at Walmart.com is only 88cents, but then again it doesn't have every band or song by an artist. I used to have a Zen, and I used Walmart, but it didn't have alot of albums from different bands I like. Now I have an Ipod, and I am much happier! So I choose......Ipod!
I-pods do play more files and there not MP3 players, so, do Zunes do the I-pod files? If so, they're less expensive, maybe even better... But I don't know, thats why I called on your unlimited knowledge.
iPods are more expensive, but totally worth it. If your worried about size just get a shuffle, they have that new one that's about the size of a quarter. Like what's been said, iPods can use more than just MP3, so as an owner of multiple iPods (over the course of since they came out I've cracked a screen or lost a couple, nothing to do with the quality of the iPod)I choose iPod.
