Nintendo, your DS has tons of games, a wide variety of unique stuff that's a blast to play. Sony, your PSP is a gadget-lover's gaming tool, with everything from Skype to Internet-radio support (oh, yeah, and you have some cool games, as well). But unless you both do something in 2009, the iPhone and iPod Touch will soon become the top dogs in handheld gaming."
