The true heir to the iconic Game Boy isn't Nintendo's 3DS. It's Apple's iPhone, iPod Touch and iPad, three gadgets that are, among other things, impressive handheld gaming consoles. Nobody else covers games for them like Touch Arcade, a blog and twice-weekly podcast. Whether you're into puzzles, shoot-'em-up or nostalgia, its reviews are a cogent, reliable guide to the gems (and duds) among the 75,000 or so iOS games available in the App Store. Its busy forums are worth a visit too.
