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.
The iCADE costs $99, which is pretty reasonable considering the thrill of Atari's original controls. While we love playing classic games on our iPads, the touchscreen just can't match the button-mashing goodness of a classic arcade game.
Pre-orders are available now for shipping by May 10th within the U.S., and the iCADE will become globally available thereafter.
