I'm hoping you guys can help me out. I've been reading some interesting articles over on BBC's news site on DRM. It seems many people are upset about limitations used by companies like Sony and Apple's iTunes. What exactly are the limitations on music you buy from iTunes? I don't use iTunes to buy music, though I do use it to organize the music I obtain from other sources. I'm very interested in this, especially since many of my friends buy music from iTunes.
