For several years running, Nintendo has been buried in cold, crisp cash -- its executives unable to emerge from beneath the mountains of money. The heavy cash storm has been raining on the company's Kyoto, Japan headquarters relentlessly for two reasons: Wii and DS. Well, three now, if you count the recently released DSi handheld, which has reignited interest in the platform in the homeland and merely proved a worthy alternative to the DS, which continues to be successful, elsewhere. Combined, these platforms have made possible hilarious money fights between Nintendo's global president Satoru Iwata and legendary game designer Shigeru Miyamoto -- or, so we like to think, anyway. That's because up until recently there hasn't been much competition, especially in the handheld sector where Sony's PSP has, for all of its impressive technology, languished in distant second sales-wise. Now, though, Nintendo's handheld dominance may have a new threat from an unlikely competitor: Apple.
