Recently, for a week, I had a Gameboy Advance SP.

Overall, mainly because of the backlit screen, I'd give it the nod over my Gameboy Color, although I prefer the simple 2 AA batteries the GBC uses, and the fact that the sound is better, at least on the older games (try playing "Gauntlet 2" on the Advance).

What I don't understand is why Nintendo put out 3 units: the DS, the Advance (which needs a wormlight, just like the GBC), and the SP.

Why did they not simply backlight the Advance, or just put out the SP? And is the DS really that special?

Anyone?
