What portable music player do you use when you ride?

I'm looking to move into one with a lot more gigs. I've not owned an Ipod yet. I heard they could skip a bit when jogging, cycling, etc. Not to mention. the classic (most gigs) are so big. If anyone uses this one, how do you secure it while riding?

I'm not interested in hearing how unsafe they can be, I'm aware of the necessary precautions. And, it won't be used all the time.

I do greatly appreciate any and all input.

Thanks so much.
