When I saw the home sharing, I thought... "Finally!"
But then I was thinking, what about between accounts on the same computer? Right now, there are a few ways to either share everything, including apps, ratings, but playlists, but it's not exactly elegant... and over time I've realized that I want to share most, but not all of this information. In fact, I've gone back to simply syncing both iPhones to one user account.
Will this feature make this better? If so, will I still have to duplicate all the music (copy?) or is it smart enough to "just work".
We'll see.
