I posted a link to a MacWorld article
here.
Really, you'd be better off buying a RIO or some other MP3 player until you can afford the original iPod. The $99 is equivlent to something released by other flash companies 4 years ago (from the article). No screen display, doesn't come with accessories that come standard with other MP3 players (so if you want an armband add another $20 or so to that $99, if you want additional storage space add another $15-$40 for flash cards). By the time you are done buying stuff for it you could have bought a 15gig iPod.
