We had a video-conference with Cols at Gen San using the Samsung Smart TV on our end (and its free webcam), and the Samsung Galaxy Tab on Cols' end. It was pretty interesting to do a Skype session just using the TV and the home Wifi system. Navigation is pretty simple once the account is setup.
I taught Caitlin how to do it so that she can initiate a Video Call when I go to Gen San also tomorrow. She can probably figure out how to do it on the computer, but this one is simpler. She just uses the TV remote to initiate a call.
