Is the PSP considered successful for Sony?

[Ajax]

the PSP had brought us one of the best and most wel designed handheld games of the last years; Crisis Core..

so you can say what you want,
but the PSP is a handheld for guys like me
cuz I'm not playing Animal Crossing, Brain Training, FFIII, Math Training and New Mario Bros. on the NDS.. hell no..

just give me Crisis Core, Wipeout, Echochrome, Tales of Rebirth, Suikoden, Tactics, God of War, Pro Evo and Wild Arms..


so just like the Wii and PS3
the NDS and PSP also have different libraries that appeal to different people..
