I've got the 60GB iPod video and bought a nice case to keep rain/dirt off of it. Working nicely so far. Wife has a new Nano and the 1st gen shuffle - both really nice. She takes the nano to the gym every day so it seems to be holding up well.
I think the case you put them in makes all the difference in how they hold up.

Thats one thing I like about the Zunes. They have a rubber coating over them. So a case isnt really needed, but it would help.
