It seemed completely unecceccary, what's wrong with the original DS? Nothing.
You think there was nohing wrong with it? Dirt got caught between the console and the screen, so the touch screen couldn't be calibrated properly. I myself owned an original DS until the touch screen was so bad I couldn't interact with some of the screen, so I got a DS Lite which has a barrier to stop that happening.
I think it was stupid to even make a DSi or even a DS lite.

All the DS lite did was make the screen a little brighter and smaller.
