So I've seen a few of those "what do you want next from Apple/next iOS/next iPhone, etc" posts and a lot of people seem to request iTunes cloud ... I've seen the articles that talk about how it looks as though Apple would be leaning towards that direction soon. I guess I've been seriously out of the loop, or maybe it just doesn't click with me .. but could someone explain to me what iTunes cloud is? What it would do? What are the advantages or .. why do people want it so bad? I don't think I quite understand the whole concept to be honest ...
