This isn't even an appropriate question...this isn't two people's opinions, nor is it really two sides of an argument. One has a want (the DS), the other has an opinion (about a boy having a DS). So there's really no 'right' person nor a 'wrong' person, however the guy wanting the DS is right. I know many guys that own DS', and not a single one of them owns Nintendogs or Style-anything...they have Mario Kart, they have Dragon Quest IV or whatever, Final Fantasy IV, Chrono Trigger, etc...and they did not grow breasts. Proof.
Bah!
