According to Reggie Fils-Aime, Nintendo of America President, the Sony PSP Go may have fundamental concept problem : "who is it for ? "and "what's the benefit ?". "I have the utmost respect for all our competitors but it's interesting to try and answer the consumer question of 'What's in it for me in that product ? ' he said.
Nintendo is also facing competition from Apple : "the DS, with it's dual screen, offers an experience that cannot be replicated on a smartphone".
