As I was loading some stuff on one of my daughters' DS, I began to wonder, how do most tempers use their DS. Of course, with all the fancy flash carts and moonshell, you can play music and watch videos, but do you? So, do you also have an ipod, or do you use your DS as your mobile mp3 player? On long trips, when you take your DS (which we all do), do you load it up with some of your favorite TV shows/movies for viewing in the car or airplane? The core question is: Are these cool flash cart/moonshell features just a mere novelty, or do you use them in your everyday life?
