> I haven't seen a portable first-person game done well on any platform
Not 1st person but close enough: try Dead Space on iOS. Mass Effect Infiltrator is close behind (and recently got a nice update regarding free aiming). Both nailed touch input for this class of games, avoiding the "shoehorning an on-screen gamepad emulation" kludge entirely (like e.g Max Payne and GTA games, which I did not buy, because the show-me-a-gamepad-on-screen is a dead giveaway of a milking-the-cow release).
As for PSP, it lacked a second stick. Their decision of a single stick design was braindead, especially given the PS/PS2 experience Sony had.
