Wired:
Apple’s iPhone is changing the way we buy and play handheld games. Small wonder, then, that both Nintendo and Sony are pushing game downloads as the next big thing on their portable players. On April 5, Nintendo will launch its DSi hardware in the U.S. The big feature upgrade: Internal flash memory, and a slot for a SD card that will allow users to buy games online. And Sony will be putting much more muscle behind its online game store for the PSP, which has languished.
