PSP already holds 28% of market share

Some reviewers have reveled in the fact that the Nintendo DS is outselling the PSP. Fair enough, but remember that the PSP is a younger system, and has been out less than a year. In light of that fact, the PSP securing 28% of total market share, while Nintendo has been in the handheld biz for over a decade, is quite a feat. Analysts expect the PSP's presence to continue to eat into Nintendo's handheld dominance.
