Sony, for its part, is working to make that secondary display massively more appealing -- the company's latest generation of high-end camcorders adds an HDMI input, with an option to display content from any compatible source (a full-size adapter ships in the box).
The Gigabit Ethernet adapter adds a Gigabit port to your MacBook Air, MacBook Pro with Retina display or any other USB 3 enabled computer and provides a fast and secure wired connection without hassle of Wi-Fi setup.
