Query: The features and uses of your DS (and free sleep mode)

The ds has a lot of new functions such as a touch screen, voice control, stereo/surround sound, and my favorite anytime sleep mode. The don't tell you about the free sleep mode but they should. Basically during any game any time just flip down the screen to pause it and flip it back up to keep playing, no matter where you are or what you're doing. This is also great when you use it as a makeshift alarm clock (like i have had to bafore as it will help u conserve battery life). And the great 3D grphics (or polygons) make sure that you will not be dissapointed if you can only afford the DS vertion of some of your favorite games. And also later on you will have INTERNET PLAY! which will be a lot of fun. And i'm sure you can get all the other features from the other 300 reveiues out there but I told u about the sleep mode now didn't I?
