Do you like wasting money? Sure we all do. So why not buy an iDevice game control pad that will work with two whole games (Bugdom 2 and Aftermath) for the low low price of $49.99? Get yours before they get discontinued.
To be fair, it is a neat-ish idea. The upside is that this ten button controller plugs into the headphone jack, comes with a headphone jack splitter, and requires no batteries. Sadly the downsides seem to outweigh the gamepad—no game support, bulky, inconvenient.
