Hi,
1. If the durability is an important point for you, i would'nt recomand you the ipod touch, it's not very tough. If you buy one, be very very careful, or buy a very good case, or both, cause mine has been reak when i droped it from 1.5 m. from the ground on a hardwood floor. I don't have a zune, i'll probably have one in a couple week, so mp me in something like a month to have a feedback or/and a comparaison on the durability.
2. all your songs are in WMA ?!? don't even think of an iPod, iTune can convert them in mp3 before putting them on an iPod, but it's VERY long, if you want to convert something like 1000 songs, you need at least 15 hours. There are no User EQ on the touch, and on the Zune there is no EQ. If you like bass, i recomand you the skullcandy Skullcrushers (even without an EQ, YOU WILL HAVE THE BASS YOU WANT ). The sound is ok, if you can find them under 90 $, they worth it. When the bass aplificater is at MAX position, they shake on your head, you take them by the headband and you feel the bass. In extra, you have a lifetime waranty, I already returned a pair cause the headband broked, and it's very simple, you send an e-mail, they answer you 2 day after, they accept EVERY e-mail, you just have to read the waranty paper and invent something credible or to say the truth if it's over the waranty, and one week after, you receive your product in a new box, with all the accesories, they don't repair them, they give you a new pair, I think it's a must. The only bad thing that I've notice on the skullcrushers is that they're not tough like a G.I or a T.I. of the same brand, but with the waranty, it's not a very big problem. Another bad thing ( but that point won't affect you ) is the sound quality : it's not very detailed compared to the bose headphones ( both on-ear and around-ear ), the JBL reference 510 and other stuff like that, but it's not the same price range too, if you pay 90 $ or less, it's not overpriced, and not under-priced. You say that the sound quality is not a very important thing for you, anyway, if you have ultrasone edition 9 or a cheap pair of headphone, at 128 kbps, there won't be a big difference.
3. There is a very good video quality on the touch, i don't have any other thing to say about video quality, it's good.
4. For that point, the zune is 100 km under the touch. You can Jailbreak the touch to add almost everything on it, games, utility, downloading music directly on the touch without any computer, stream media, web with saffari, youtube, internet radio, VoIP, agenda where you can add frends' info directly on the device ( very usefull function ), google map, gmail, etc. The touch is way better on that point.
5. You can rearange playlist order, add or delete a song on a list that you made before, you can't delete or rename songs from the memory diectly on the device, but you can delete videos on the device.
It should help you a little bit.
English is not my first language so you'll maybe find some error, but i did the best I could.
