Wow. Kinda sad, to hear this. If the DS is a 'kiddie toy', as he seems to be implying, why has the DS utterly crushed the PSP in the handheld market? The fact is that Nintendo has managed to court more developers to make more games for the DS, many more than the PSP, which is good for little more than a crappy media player now compared to the DS. Oh, sure, there are games on the PSP that are good, but the number of good games on the PSP pales in comparison to the sea of A ranked games on the DS.
I am 21 and I play a DS. I'll keep my DS over a PSP any day; there are more games on the DS I enjoy than there are possible games on the PSP that I would want.
