I have 9 yr. old and 7 yr. old boys who are video game finatics!!!  They have their PS2 at home but for long distance trips in the car...it was horrible!!!  We decided we wanted to get them some portable game systems for our frequent trips back and forth to St. Louis (2 hr. ride) to help keep them occupied.  The DS's have pictochat, they can battle each other on the same game with only one game chip.  The graphics are awesome and most of all...the kids LOVE IT!!!!!  These things even come in handy when they are fighting.  I tell them I do not want to hear them fight and they put the pictochat...
