I want this. This and gamepad support for more mobile games.
ThinkGeek unveiled a new iCADE device at the 2012 Toy Fair in New York City this week. The iCADE 8-Bitty is a retro-style d-pad controller for iOS and Android devices. It features a very NES-like layout, but has eight buttons, including a shoulder set. It's battery powered and connects to your device wirelessly.
ThinkGeek.com will offer these controllers later this year for $24.99. We'll try to get our hands on one of these to let you know how well they work.
