If I have my mail set to push, is Fetch necessary for any other apps?

Like I said, I have my mail set to push, Facebook and Twitter are obviously push, is there anything else I would need to leave Fetch on for or should I just set it to manual to save battery?

Either apps have push, or you have to open them to use them. There's no such thing as fetch outside of email.
