i use my ipod, because i don't feel like loading all my music onto my work computer - plus this way itunes isn't open, so it's not taking away valuable system resources from my other open windows.
i just started using isproggler, it's a program that takes the "recently listened to" music from your ipod and uploads it to last.fm.
I don't know why i'm doing this, since I can't figure out the point of last.fm ... what is the point?
