Initially the system will allow file-sharing with Sony's PSP games console, Nokia's N-series mobile, Sony Ericsson's Walkman and Cybershot handsets and Microsoft's Windows Mobile smartphones.
Nintendo will have to wait and see whether these titles can help maintain their dominance in the handheld market with the upcoming Nokia N-Gage, Sony's recently announced PlayStation Portable, as well as improving mobile games.
Sadly, the iPod, iPhone, Zune and Windows Mobile aren't supported yet, but the rest of the device list is pretty decent: it includes the BlackBerry Pearl, Storm, and Curve, the G1, Sony Ericsson Cybershot and Walkman phones, the Kindle, Nokia N and E-series phones, and most digital cameras and flash-based camcorders.
