S4Rs

One of the coolest features I think is that with the dock you get a full size USB. You can then plug a ps3 remote in and it will sync with the prime via Bluetooth. And then you have a wireless game pad to play shadow gun with and will work with all tegra 3 controller approved games. I did notice problems with audio on my prime though if I used a Bluetooth headset and game pad synced at the same time.
