I'm honestly happy with the original DS. I know the Lite has a brighter screen and longer battery life, and the DSi has all these brand-new updated features, but when you think about it, the Lite is too small for some people (like myself), and the DSi's battery won't last nearly as long. Add to that the fact that the DSi removes the GBA slot (what will happen to Guitar Hero?), and I've concluded that neither are worth buying to me right now.
