Ok I can use folders on my main screen. So I've gathered my Twilight into one, my games into one and the default ipod apps that I never use into one which is fun. I understand the multi app thing now but its just for music. Like if I was using an app I could double press the home button and a lil pop up box woul come up with pause and skip buttons. Saves having to come out of the app to do it.
The double press thing isn't new! You can do it when your iPod is locked too.
