Own content storage is a mess.
I think there should be ONE CENTRAL PLACE (or the option to handle it that way) for all media you create.
Then, all project files, edits etc done to your media should be stored in there as well.
I like how iPhoto and Aperture can share libraries, so you already have a kind of centralized approach for photos here, however, movies are a mess, you now have home videos in iTunes, iPhoto/Aperture and maybe some projects in Final Cut or iMovie.
To make things worse, you might have a nicely edited movie you'd like to sync via iTunes, but unless you actually create another big big storage hog an exported movie is and add it to say Aperture, there's no way to both sync your photos and say a couple of edited videos.
meh
Anyhow, I plan to use the home movies section for now for stuff I get from friends, so iTunes is constantly the place of all things coming TO me and not from me.
(Apart from photos people send me... Where do I put those logically? Aperture I actually tried to keep 100% to my photography and videos and I wanted to use iPhoto for that originally, too bad you cannot synch two programs with iPhone. Oh Jesus...)
