You guys are right, I was addicted to the PSP at first because of its great graphics but since I had a chance to play Retoku Tower (something like that) and some other games, I realized that the graphic of PSP is not as great as Sony had already annouced (somehow I thought that Sony was lying to the fans cus they was always saying that the PSP's graphic is as good as PS2) and another reason is that most handheld-gaming-system-owners in my country (Vietnam) is ownning PSP and they're very proud of it. So, I thought DS is just familiar to GBA or it is a GBA with crappy 3D graphics and 2 screens.

But as soon as I got enought money to go to the store and pick a PSP, I began to reconsider the DS cus I always have a crush on Mario, Bomberman, Castlevania, Wario ..  and I realized that none of the PSP's game suited my style. Then, I pick 2 white DSlites (1 for me and 1 for my little sister) and our family have always been full of laughings since. I often play Mario Kart DS with my family members and yes, IT's DAMN FUNNY! Now I'm sure that my decision was not wrong.

 Thx Nintendo very much for bringing a lot of fun to my family !
