Mark Cuban has used his dotcom wealth to buy Landmark Theatres.  I've had an HDTV for a couple of years and have had an off-the-air and DirecTV HD receiver for about a year.  I appreciate what Mark has done with HDNet, although the content is still pretty weak across the board.  I can't wait until we get an HD Tivo, though... that will be the killer for me, as KC and I are both addicted to Tivo.
