At the time we, like many others, dreamed of how cool it would be if it was a real dock that turned your iPad into a mini arcade cabinet. We even suggested in that post a few ways this could be done for real using MAME.
Now, ThinkGeek has partnered with ION to make a real cabinet/controller to make your arcade retro gaming dreams come true. Rather than using the dock connector though, the iCade is a Bluetooth controller for compatible games, of which we imagine there will be quite a few in the future, but for now they have set up a partnership with Atari and their fantastic arcade game back catalogue.
The iCade doesn't look quite the same as the original mockup, but it does still look great, and the cabinet includes speakers which theoretically can be used for any media, meaning the iCade could double up as a dock for playing back any of your media.
At $99 we think the price is a little steep, but we are sure they will sell a load of them to sad geeks like us who constantly hark back to the days of wireframe graphics and relatively simplistic gameplay. Check out the iCade in action at CES in the Wired video below and be sure to let us know in the comments if you will be queuing up for an iCade in the Spring.
