Hi All, I was wondering. I know that iTunes now allows you to download previous purchases you have made to you computer. In fact, I am doing that now. However, I have some noob questions as to how it all works. As I understand, Cloud will now allow you backup to the cloud and use the cloud and a central repository for all your devices to access your music etc. Therefore, is there a reason to download music to your computer and use up all the hard drive space if you can utilize it from the cloud? or do I just have a fundamental misunderstanding of how this all works? Please provide an overview if you could.... Thanks!
