I own both the Nintendo DS and the PSP. You can’t call someone a fanboy when they own every console on the market, have played them all and then form an opinion on what is better and why.
I love Nintendo. They’ve been entertaining me for almost two decades now. However, “Well, the DS will be a great system, with great games, in the future” just doesn’t fucking cut it for me. When the DS starts coming out with some decent titles, I’ll reevaluate my opinion on the system. But until then, it’s just no match for the PSP.
