Nintendo DSi XL. what do you think?

[winstonsam]

Hello friends,
My sister has a DS lite I get to use when I come home for the summer and holidays, but I've had an original DS for a long while now. I was planning on getting a DSi, but now that the DSi XL is coming out I'd rather default to even bigger screens. What confuses me is that apparently an XL costs more than a regular DSi? Even though the screens are bigger, I've just gotten used to the idea that smaller technology it means it is more expensive, so I was expecting bigger technology but less expensive, or at the least the same price.
