[citation][nom]jerreece[/nom]Yeah.... I was given an iPod Shuffle for free (only reason I own one). I'm fairly certain it's smaller. Plus it has a built in clip to hold it to your shirt/pants.[/citation]
Not really designed for running. I returned one because sweat gets inside through the cable hole and started short circuiting the middle button which does play/pause, skip, title "shout" depending on the number of times you press it... so imagine running and suddenly it starts changing tracks and shouting song titles out of the blue. It's almost like they did not foresee that such small size would make the Shuffle a nice option for exercise, and completely forgot about isolation from humidity.
So anyway, yes, I think shuffle is smaller (although useless) xD
