Ipod or mp3 player?

i have an Ipod but it can only stores 500 songs, i find that okay for me. i use it everytime i travel going to work. i ride train two times so i need my handy ipod to keep me company. i also have songs on my celphone but not that much, my cellphone is too important for me for communications that i dont want to see it on battery low when i play the music. so i would rather have my ipod for music and my cellphone for communication

Iam pursuing my graduation. Iam having an Ipod. Iuse it very often while travelling, in leisure time etc.,. one more thing is i also use for practicing TOEFL.

I have a few iPods and I use mine everyday - mainly at the gym. One of them I use as my hifi by compressing all my music and having it all on the one iPod and then attaching it to external speakers. It makes it easier to look for music you want to listen to rather than having to sift through loads of cds.
