GameDock

Now, if they could only market this in a way to convince gamers that the iPod/iPhone/iPad are suitable gaming devices/platforms, this could really take off...

"Let's face it: as good as gaming on the iPhone, iPad, and iPod touch can be, it's still lacking one critical element: tactile control. The GameDock ($125) is meant to rectify the situation by turning your iOS device into an old-school console. Thanks to two front-mounted USB ports and an outgoing dock connector, you can play nearly any iCade- or dock-ready game in full HD glory on your TV, using actual controllers. As anyone who's tried to play classic ports like Sonic, Street Fighter, or Mega Man can attest, it makes all the difference in the world." - Uncrate
