Originally an April Fool's Day joke by ThinkGeek, the company has actually turned it full circle and produced a working model of the iCade. Best of all – it's soon going to be available to buy very soon.
As you might have guessed, it's a vintage-style arcade cabinet for your Apple iPad. Produced in conjunction with Ion and Atari, the iCade uses Bluetooth to communicate with the iPad, transferring classic arcade games (like Asteroids for example) to your iPad screen, arcade controls giving you a genuine arcade experience. The APU is going to be released too, allowing any Apple developer to create iCade-compatible games.
Lokk out for it from April (for real this time), priced at $99.99.
