I have one of those. If I were you I'd avoid it unless you're content to load it via iTunes (which is the way it works). In terms of toons ... Say 3 to 4 hours worth? There's no screen to identify what's playing; it just rolls through them in the order that you loaded them or shuffles them about.
I find it ok 'cos I can load what I want, when I want to whether it's tunes, spoken word, or whatever.
