This is the cool looking Atari Arcade – Duo Powered joystick device, it is clear what it does and of course, there is another similar device around. However, this is not like the others, for one thing it is made by Atari and it works with the great iPad app Atari’s Greatest Hits. You do not get a cabinet feel to this device, but you do get a retro controller to play retro games on, it is like time travelling for gamers.
Information on the device and more importantly the price are a bit limited, which is a bit of a shame.
