Stories of the PSP's failure in North America are greatly exaggerated.
I see what you're saying, but I dunno... I guess I'm just a fan of comparative economics. I mean, whenever people complain about the price of gas around here, I'm always like, "dude, have you ever been to England? Or how about Japan? Gas prices here are freaking CHEAP!"
I suppose the 3DS has indeed one-upped the Vita in terms of cheap memory, but to me, that always felt more like Nintendo undercutting themselves than Sony overcharging. I actually feel the same about the 3DS itself: I think he original $250 pricetag was totally fair, and that Nintendo's basically lowered the price far more than they had to.
