So, you’ve got a DS; you’ve got games; you even have a WiFi dongle; what now? Why not upgrade your stylus.
The Nintendo of Japan website has a stylin stylus that will give you a better grip on things. My translation is a little rough, but I think the page says “Very cool, colorful stylus for you.”
Actually, now that I look at it, I think it only holds your stylus. It’s still an upgrade and still cool in my book.
