The DSi camera offers no zoom feature and the audio sound for taking pictures can not be turned off (Unless you put in your own switch for the speakers.). Other then that the camera offers several activities that will keep most kids entertained for a few hours. For adults it could keep your interest for a short while unless your like me and like taking pictures out of your peep hole.
Another nice addition is the ability to swap game cards without turning off the power and press and release of the power button (Now moved inside instead of on the outer top) puts you back to the DSi menu. The menu is another clone from the Wii.
Something strange I came across was that if you hold down both top triggers and the start and select buttons then turn on the DSi you end up at the calibration screen. Wonder what other little short cuts exist.
At the moment no carts exist to allow homebrew on the DSi. Something I'm sure will be fixed shortly. The DSi also offers no mp3 or video support. When is Nintendo going to catch up with the times and trends and make their devices competitive with the rest.
The DSi also offers no text/e-book features and does not work with gba cartridges.
The new matte finish is kind of nice, no more smudges on the shell and it allows the camera on the outside to blend in. But it still has a ways to go before it becomes my portable device of choice.
