SIGNAL's RP One is designed to be a standalone game controller that connects wirelessly to all current iOS 7 devices. It's meant to evoke the feeling of a console controller - with an ergonomic design and size that should be comfortable to a variety of hand sizes and a number of controller inputs like dual sticks, a digital pad, face buttons, and triggers.
The RP One also comes with a universal stand/charging dock meant to accommodate iPads, iPhones, and iPod touches as well as many of the cases they might be nestled in. Combine that with the option to use both the RP One and an iOS device while they charge and it's essentially like a home console. Of course it can still be used on-the-go and allows for up to 10 hours of continuous play.
The RP One will be available some time within the fist half of 2014 and will sell for $99.99.
