I have seen the future, and it is wireless. Wireless data, wireless music, wireless speakers, wireless keyboards, and now, wireless HDMI hi-def video. (Of course, all these things still need to be plugged into the wall, for AC power. Perhaps, somewhere on the Other Side, Nikola Tesla is still working on that.)
Wireless HDMI gets us that much closer to the Jetsonian ideal of the sheet-of-glass video screen floating unencumbered on a wall – without having to tear down that wall to run wires.
