1.- Lack of flagship titles; PSP games like LBP, Motorstrom, Killzone, Dante's Inferno, etc. are considered "The lil' version of their console counterpart" PSP needs something like Monster Hunter in Japan or Pokemon for the DS
2.- That terrible idea of selling the PSP as a multimedia device instead of a full gaming handheld.
3.- Piracy, hacks, mods, etc.
4.- The price, specially that PSPGo thing.









But I bet that a pricecut is not far off now anyways ( my best is E3
