The first Japanese ad for the DSi not only reveals who they're really targeting—the really young and really old—but a secret feature. In addition to the whole camera and wacky photo editing it's got going on, it's also a digital picture frame! Perfect for grandparents to display wildly distorted pictures of their grandchildren scribbled with embarrassing notes. Oh, and I think might play games too. Maybe?
