Japan - Just as Nintendo was once synonymous with gaming in the way that Kleenex is synonymous with tissue,* Game Boy was used interchangeably with handheld gaming for more than 15 years. So when the data comes in showing that Sony's first entry into the handheld market has captured and held 30% market share or more for over six months, it's no small feat, especially when considering that the DS has overtaken the PS2 for greatest selling system in Japan, ever.

* How many other products can we say that about? Maybe the iPod for MP3 players? Twenty points to the reader that can name another product where the branding is synonymous with the product.

Oh yeah. Tussin. That's mine.

Clearly there are several issues that factor into this, including the much larger handheld market, the costly entry into hardcore gaming this generation*, and actually having a viable competitor to the Nintendo product**, but Sony's foothold in the market can no longer be denied.

* By hardcore gaming, I mean the ability to play a majority of games from "hard core" franchises on a single system.

** What? The Wonderswan? The Taco Phone? The Game Gear? Somehow, against gaming greats such as those, the PSP was only the first to seriously challenge Nintendo in the handheld arena.
