That iCade Mobile iPhone/iPad controller attachment thingy we first heard about at CES has made it to retail for 10 dollars less than what was originally announced, which is always a welcome surprise, retailers.
The device, now available at Think Geek for $70, features a d-pad, four face buttons, four shoulder buttons and allows for the phone/pod to be set in either portrait or landscape. The enclosure connects to your iPhone 3, 3G, 3GS, 4, 4S or third/fourth generation iPod via Bluetooth and works with any iCade-compatible title on the App Store. It's also works with iMAME4all, a MAME emulator available for jailbroken iThings.
