Nintendo DSi Teardown Report

Since the kids have the DS Lite (previous generation) versions, it's kinda cool to see what upgrades and new features Nintendo stuffed into the new model.

 - The DSi has an integrated SD/SDHC expansion slot. 
   You can now use a normal SD card for the playback of AAC audio
   files and external storage of pictures or downloaded software. 
   Can anyone say homebrew apps?

 - Two VGA CMOS digital cameras (0.3 megapixels); one on the 
   internal hinge pointed towards the user and the other 
   in the outer shell.

Chips of interest, left to right and a view of the rest of the DSi in pieces, and a teardown of the original version. (NOTE: Clicking on the images will bring up larger versions)

 - Samsung 1st generation MoviNAND KMAPF0000M: 256 MB NAND Flash and MMC controller. 
 - 82DBS08164D-70L: Fujitsu Ltd 128-bit FCRAM (fast-cycle RAM).
 - Nintendo's custom ARM CPU.
