Father of PlayStation Admits Sony Mistakes
News for nerds writes "Following the news of Sony slashing its profit forecast due to the underperforming AV & PC divisions, Ken Kutaragi, president of Sony Computer Entertainment Inc. (SCEI) known by the PlayStation brand, admitted he and other Sony employees have been frustrated for years with management's reluctance to introduce products like Apple Computer Inc.'s iPod, mainly because Sony had music and movie units that were worried about content rights. The PSP by SCEI is one of the first Sony products that support non-proprietary standards such as MP3 or H.264, and now SCEI considers opening up the UMD disc format employed in the PSP."
