personnaly i hate the spinny wheel thing and itunes so i don't really like ipods. But i would consider getting an ipod shuffle because it is small and does everything i need to except ipods don't have expandable memory (they make you buy a new one instead) and like i said before i hate itunes. And there is a new ipod every couple months so you have to spend even more money ontop of that already overpriced mp3 player. I'll stick with my mp3 player and my cellphone.
It's a tough call which is my favourite. But I'd have to say the 2nd Generation nano is my fave. The video is good because it's got lots of space and plays videos(obviously) and the nano is nice and thin and looks killer.
