IPOD or MP3 player?
I trying to make a choice and my knowledge is zero in this area.

1-I would like to play back for my own listening pleasure.
2-Possible play songs using the keyboard imputes.
3-What are the major differences?
4-What is your personal preference?
5-I will be recording songs with my keyboard and saving them as MP3 in order to share them with other members.

Any help would be appreciated.
