ipod for sure. zen is oversized and overweight and has a lousier interface. other ones don't do much better. the price difference isn't much really, its not as if ipod costs X more when competitors have products that match or exceed ipod. competitors still are inferior in many ways. when you've got thousands of songs, interface matters. when ipod is barely small enough..(to me) being quite a bit bigger like zen just kills the justification of spending hundreds. none of em are free, if ur gonna spend, spend right
