I don't have an iCade. Though a tiny custom arcade cabinet for my iPad is a lot more attainable than a full-sized arcade machine, it's still far enough into the "frivolity" category that I haven't made the plunge ... plus, I don't have an iPad, and the iCade is a bit cavernous for my tiny phone.

The 8-bitty, produced for Thinkgeek by iCade maker Ion, takes every bit of the iCade's functionality, and shrinks it down into an affordable, portable, and iPhone-friendly control pad. Nobody on Earth actually needs a gamepad for their iOS device, but this is as close to practical as one is going to get.
