I understand why some people like taking their console games away from the TV, but i am not one of them. I like a good handheld game, but I like them to be different from what I can get on a console for the TV. I like the stuff made for handhelds: smaller games, casual games, games you can play in short bursts.
I think Machocruz is right about Nintendo being perfectly matched for a handheld experience. MS and Sony maybe not so much. They are too determined to offer the best graphics possible. You just can't do that cheaply on a small device. I can see them coming out with some sort of tablet, though, that might let some games be played remotely.
The biggest reason handhelds have sort of fallen away is, of course, phones. All the casual fair and shorter games have gone there. No one's going to compete with that.
