If you're tired of having to pause games on your Android mobile device just to wipe finger grease off the screen, you are in luck. For $80, the Bluetooth-connected Razer Serval gamepad will ensure that you never touch that screen again (at least until playtime is over). Razer initially announced the Serval back at CES in January but it has finally hits Google Play's virtual store shelves.
