i own a archos and an ipod, and i have to say that i LOVE the ipod. it's the best.
somebody mentioned that it's not worth the money...you are not exactly usin the 'ol brain cells there, are ya? the ipod fits alot of songs into a tiny space, whereas a CD player must A: be huge because of the size of the CD, B: requires a big-ass case to carry all your CD's, and C: isn't as easily portable as mp3 players are.
i also have a very nice sony cd player, and to be perfectly honest, i can't stand using it anymore. i like the fact that with my ipod i have instant access to over 700+ songs, without having to fumble through a huge case of CD's trying to find the one i want to listen to. and a big argument against HD mp3 players is that they skip constantly. well, the archos one that i have skips if you move it even a little bit, but i have yet been able to make the ipod skip, and i mow the lawn and jog with it.
anyways, that's just my opinion
