If you want to play up to 100 arcade classics on your iPad or iPad 2, then Atari has provided a great opportunity in the form of the Atari’s Greatest Hits app. You get Missile Command for free, and can then download up to 100 arcade titles for as little $15.That’s great on its own, but doesn’t give you the true arcade experience of buttons and a joystick. So Atari has also come up with a new peripheral called the Atari Arcade that turns your iPad or iPad 2 into an arcade cabinet.This is by no means a new idea as ThinkGeek have been shipping the iCADE accessory for $99.99, a product that actually started out life as an April Fools joke much like Canned Unicorn Meat. However, Atari’s version only costs $59.99 offering a $40 saving for effectively the same experience. That saving is likely realized as the Atari Arcade actually plugs into your tablet where as the iCADE used a Bluetooth connection.Your iPad or iPad 2 just slides into the Atari Arcade and offers up access to a joystick and four buttons–ample for the classic games it is compatible with. Atari believe using the cabinet controls instead of relying on the touchscreen offers an “accurate and speedy response.” We hope that’s the case as some of those games are very difficult if accuracy and timing can’t be easily controlled.The Atari Arcade has been developed in conjunction with Discovery Bay Games who have a range of Duo-branded accessories for iPad. It is available from today in Target, after which it will be available in Apple Stores and Toys R Us from November.
