The back panel also houses the rest of the connectivity options and there are no surprises from what was announced at Logitech's press conference. The HDMI input is for connecting a cable/satellite box, while the HDMI output will connect directly to your HDTV or AV receiver.
We've already commented that we feel that Logitech's included keyboard appears to be the best way to control Google TV so far, and our limited early experience with it has mostly proven that to be true.
One thing we weren't expecting was an HDMI cable included in the box. Despite HDMI cables being cheap and necessary for home video devices, few manufacturers include one in the box, so we applaud Logitech for tossing in a cable.
