Nothing to do on 18 hour flight!?

I am 13 years old, and in 4 days I am flying from Boston to Australia on United. On the plane, I am afraid there will be nothing to do. There are no seat-back televisions, and there are only 4 in-flight movies to watch, and I only like two of them (Gulliver's Travels and Narnia). I thought that there was going to be outlets on the plane, but then I saw it was just for First and Business class (We're in economy). I already was uploading tons of movies onto my laptop, so now I'm pretty bummed.

I have 2 good books I REALLY want to read, my ipod touch (up to about 3 hours of battery), my laptop (up to about 3 hours of battery), and my Nintendo DS (idk how many hours). What else should I bring with me?
