Playing games on iPad by using its own touchscreen maybe is not enough fun for you. Sometime, we just need a controller to play a game. After all, we are get used playing games by the the controller on PSP or Nintendo. If you looking a cool game accessory for iPad, this iCADE might be the one you are looking for. The iCADE is a retro-looking dock to turn your iPad or iPad 2 into a classic nostalgic gaming machine.
About the size of a desktop computer, the iCADE connects to your iPad via Bluetooth, so all you have to do set it down and boot up the time machine. Atari’s Greatest Hits, available from the App Store, is currently the only game to support the Bluetooth-connected controls. But after the iCADE is released, they will release the API so that other games can be adapted.
