Mine works fine, and sounds great. Take it back if you're not satisfied, and if they ask you the reason, just plead distinguished mentally-challenged. It's not like you would be lying.
My creative Zen Nano works fine and sounds great, too. Both my Zen (1 gig, $49.99), and my Sansa (4 gig expandable to 6 gig with microSD, $129) have FM, FM recording, voice recording, and I can play video on the Sansa or listen to audible audio books on the zen. I can even rip Cds straight to the Zen with the built-in line-in jack. I can do none of these things with a Nano, which has less storage space (in the case of the Sansa), and costs more than both. Plus, I've listened to Ipods before, and the sound quality isn't that great. Fuck an Ipod. Apple may make good computers, but they've huckstered everyone for years with the iPod.
