SteelSeries introduced the SteelSeries Ion Wireless Controller at CES 2012. The Ion is designed to work with PCs, as well as touch screen devices like tablets and phones, and connects wirelessly via bluetooth.
The Ion measures about the size of a standard deck of cards (approximately 108mm in length, 55.5mm in width and 18mm thick) and includes a rechargeable, lithium battery that will provide up to 20 hours of wireless use and can be plugged into your device for charge and play use.
Other features include 2 mini-joysticks, a left side Dpad button, 2 trigger buttons one at each shoulder, and a four button layout on the right, similar to familiar Nintendo, Xbox 360 and PlayStation controllers. The buttons can be customized.
The Ion Wireless Controller will be available in Q3.
