I should add that the PSP's biggest problem is its predecessors.
The PSP wasn't supposed to merely do well. It was supposed to usher in a new era of portable gaming, as the PS1 ushered in a new era of home gaming.
It was supposed to have overwhelming developer support, with every third party game of consequense being (mostly) exclusive to the PSP. And unlike the GC, which allowed for multiplatform games, the DS was supposed to be so weak, no developer would want to touch it, outside of Pokemon ripoffs.
Franchises, like Castlevania and Final Fantasy, were not supposed to have ANY games on the DS (outside of Chrystal Chronicles, but that wouldn't count). It doesn't matter that Chrisis Core and the enhanced remakes of Rhondo of Blood and Symphony of the Night are on the PSP. The DS still got Dawn of Sorrow, Portrait of Ruin, an enhanced remake of FF3, and is getting DQ9.
From past history, developers should have abandoned Nintendo for the better system. There was no monopoly (that was just used as an exuse once the DS pulled ahead), only a lack of serious competition, which the PSP truly is. So it was supposed to have CRUSHED the DS, not merely "got their foot in the (handheld) door".
Now I should make this clear this is not me bashing the PSP. This is a reflection of the hype and expectations of the PSP. Handhelds were supposedly in a ghetto, but Kaz Harai was not the only one claiming that. Sony fans were proclaiming the coming of the PSP all over the place. After the launch honeymoon, the drought of original games, and the flood of ports started. Until something comes along and erases the memory of that disappointment, the PSP will look like a failure by comparison, not by reality.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
