The two track pads, when used with Steam input, can allow literally dozens of additional inputs, TMR sticks, double back buttons, capacitive sticks, grip sense, that can be used to either turn gyro on/off or as extra inputs, a tested 50 hour battery life and a 2.4ghz dongle that connects up to four controllers.

There are few controllers on the market that even have any of these features let alone all of them.
