I don't. The PSP itself is a terrible handheld. While I will argue that it has some great games on it, the PSP itself is a piece of junk in every commercial way. For intelligent home brew users, it's great, but Sony does whatever is possible to stop home brew. For modders and rommers, the system is great, it allows illegal gaming on the go very easily, and Sony can't keep it in check no matter what they do. For the casual gamer, it's terrible. End users have been tricked to thinking the system is a wonderful portable media device. Now, due to stupid support of UMDs mor media other than games, the PSP is difficult to work with for the casual users who want to listen to music, watch movies, and surf the web. For hardcore gamers who support the system, they have to spend a bit of money on alternative energy sources, or switch to illegal activities to be able to game on a trip for a decent amount of time.
The PSP can do lot's of things, but it does absolutely none of them well. I agree that a competitor is important in nearly, if not all, business areas, but I have to hate the fact that the PSP is Nintendo's biggest competitor in this area, because when it comes down to it, the PSP really does suck. In my opinion, the PSP hasn't much from anything it's tried to do right, but only from it's name, which the reason there are still good games being released on the system. IMO, those games need to go to a system that can handle them for more than four hours at a time. In most cases, I don't care if it's Nintendo or not, but I do wish it was at least someone who had a viable product that itself did not rely on name alone, and Sony has failed to provide such a product, unfortunately.
I wish the GP 32 or whatever it's called now were the competitor here.
