Android and the Iphone are a threat to Sony and Nintendo good reason why !

[Millennium]

No threat whatsoever. They're entirely different markets. One could point to the number of game apps for the iPhone, certainly, but how many of these are not essentially clones of the same five basic games: Tetris, Minesweeper, Pole Position, Solitaire, and Sokoban? I am not attempting to call such games shovelware, or belittle the development effort that goes into them, but they split each others' markets up too severely. Measure the number of distinct games -i.e. collapsing all games that could be fairly described as clones of one another, or of a common ancestor, into only one entity- and the numbers are likely to be far lower.
