Query: Nintendo Ds is the best portable EVER!!!!!!!

I don't have to say much other than some of the funnest games I've played are on this system. The graphics are pretty good but its the games that make this system great.New Mario Bros.Mario Kart.Mario 64.Yoshi's Island.Metroid Prime.and more...PSP doesn't have grap on the DS.
