If it is about uniqueness i would go for Zune, if ur talking about trendy, Toshiba Gigabeat . If it is for following what other people do then get the Ipod..
Ipod. Zune is not really well settled. plus nothing beats the click wheel. once you use it, you cant live with out it.
I have a Ipod right now. Been using it for a year now, it is still alive and not a single scratch can be found on the front (scratches on the back only). Oh, and I use it just about everyday ^_^
