Nintendo DS is my favorite console, for sure. There are so many schyssta games that appeal to me, and the touch screen makes a lot of game experience (not in all games though).
However, the DSi a completely terrible unnecessary upgrade for DS-lite. Sure, it is really neat, but DSI ware (download service) is useless, and the camera is also quite awful useless.
So .. what I think this is the DSi XL a much better upgrade because the screen.
