I don't think lots of people around have either of these two. But if you know them, or own one, what would you choose? I want the Cowon D2, because of the incredible battery life, good sound quality, and the memory expansion. But I'm planning to put on lots of animes and movies on it, so it may lack some space. Also, it has a pretty small screen, so it's not that that great. The Zune 80 has the storage I want, but it's battery life is just so-so. It's sound quality is better than the Ipods, but that's not that big an achievement. It's screen is big, and I like that it has the accessories, but the video quality isn't as good as the D2. Cowon D2: Sound quality, battery life, and memory extension Zune: Harddrive, bigger screen, more accessory support. What would you choose?
