I do like my Ipod (4g 40GB). Huge hard drive, it has over 3500 songs on it at full quality. HOWEVER, here are the downsides I have found (which are common complaints)
1) Battery Life: BLOWS ASS. If you skip from song to song to song you will get MAYBE 4 hours of life. Then it is time to recharge..
2) Playlists: If you can have 3500 songs on your Ipod, and can't skip from song to song to maximize battery life, you have to make a playlist. How can you predict your listening preferences at any given time? Multiple playlists? VERY time consuming... I guess you can chalk this one up to laziness on my part.
3) Scratches. The Ipod scratches up something FIERCE.
Other than those complaints (which I do consider minor) I am one happy Ipod owner.
