I found this Game system smaller then the original DS and lighter. The thicker stylus has a good storage area. The battery has a much longer life length then any of the other techno product my child uses. I know this as I keep them charged. The touch screen is easy for dragging and placement of the game activities. There is a voice recognition which my child has used on one game "Dogs" to train them. The microphone sits in the center of the unit, For the voice recognition, make sure to remind your child to speak in a normal tone, not to shout if the pet does not understand at first. All pets take time to train, but these guys learn quickly.
Wireless communication: There is wireless communication Chat Software will let users transmit text messages, handwriting and even drawings to each other. Wireless functions could link players in the same room-or across the country.
