The J Butterfly stands out further by packing an infraredport next to the rear camera, as well as three metallic contact points for docking towards the bottom of the back side.
The gen2 unit features a sleek, all-black enclosure, but the real improvement is the addition of an infrared-out port, which provides more flexibility for customers who keep their components in a cabinet or rack.
By connecting the external IR receiver to the adapter box, and then plugging the resulting combination into a USB port, you've created an unsightly way to talk to your PS3 via infrared.
