Just in time for those retro Atari games for iPad, ThinkGeek has announced they are taking pre-orders for the iCade iPad Arcade Gaming Cabinet that started it’s life as an April Fool’s joke last year. ThinkGeek teamed up with ION and Atari to develop the iCade. ION is developing the tabletop cabinet with arcade-style buttons and joystick to hold the iPad or iPad 2. The iCade connects to the iPad via Bluetooth. Atari will be bringing many of their classic games, like Asteroids, to market with iCade support built in. Pre-order the iCade at ThinkGeek now for $99.99, and your item will ship on May 20, 2011.
