DSi 

A wannabe PSP with a reigon lock.

I love the DS Lite, but I don't like the way they are going with the DSi, they are cutting the battery life and GBA slot for a bunch of garbage. The "i" in the name also makes it seem like a ripoff of Ipod.

DSI shriek 

The universal sound made when you get killed in Super Mario Brothers or any DSI game. This sound is innate in humans, having been witnessed in specimens ranging from 3 to 63.

One more DSI shriek and you are outta this car, dude. I don't care if you are just five years old.

DSi XL 

Nintendos latest attempt to steal your money. It's the DSi with a tiny bit bigger screen and a new stylus.

If you have a DSi, DON'T get a DSi XL
