iPhone - new gaming platform living up to hype?

According to a comScore press release (thanks Kotaku), Apple's iPhone makes up 14% of all mobile phone game downloads.
The report showed an overall growth for the mobile phone as a gaming platform, but most interesting was the statistic that nearly 1/3 of iPhone users downloaded a game this past November, when the survey was taken.
Reports about the iPhone's gaming potential left early critics exclaiming the mobile phone as the future murderer of the Nintendo DS and Sony PSP, the industry's two major mobile gaming platforms. While the DS and PSP are far from feeling hurt by the mobile phone market, Nintendo seems to be taking its cues from the iPhone's tech.
The Nintendo DSi, the latest model in Nintendo's DS line of portable gaming systems, offers a downloadable Opera web browser, two cameras and an SD card slot (which replaces the Advance cartridge slot from all older models). Although Nintendo hasn't jumped the "every form of multimedia, but mobile and with its own game software" shark yet, clearly the DSi looks to capitolize on the recent trends in camera and web browsing on mobile phones as well as high demand for web books.

Nintendo has not set a release date for the DSi in North Amerca. It became available in Japan in November, 2008 and has already sold over 1 million units.
