MadCats has been working on a boatload of mobile gaming accessories. Two of the coolest gadgets we saw were a Bluetooth gaming controller and the Rat gaming mouse. Both devices connect without a dongle or any other intermediary to allow for a seamless gaming experience.
The game controller looks like your average controller, but via Bluetooth it can connect to pretty much any device and OS. The controller also boasts a phenomenal battery life. The Rat mouse is optimized for gaming and even has a retractable palm rest. It also connects via Bluetooth, but has a dongle hidden up underneath just in case.
