There are DSi only games in the works that use the camera, and there is also an added SD card slot which could add some more homebrew possibilities later or the next iteration of the R4 card. Look at games like Zelda for the DS which used EVERYTHING the system had to offer. You had to use the Mic for noise and blowing, you had to close the system to transfer things from the top screen to the bottom . . . I'm SURE there will be some cool games that use the camera eventually, then people will go out and buy the DSi. I usually use the 2nd lowest brightness, and I'd be happy with 8-12 hours.

But yeah, we'll see! I won't buy it in the next few months, but maybe next year.
