You can do plenty of things on a ds. You can Picto Chat which allows you to communicate with other people close by.(like 52 feet) If you have purchased ds games, you can play those. You can also download games from people close by. A good example is Mario cart. The person who has the game can let you download it from them. The DS IS AWESOME (until its rendered obsolete)

No, you cannot use Skype on the Nintendo DS
