Maybe we won't need a portable storage medium
I think what he might be saying is we just won't need a portable storage medium at all except for our personal recorder/players. In ten years you'll probably be able to have thousands of movies, songs, etc, right inside your computer, portable player or tivo type movie/music box, and if you wanted to transfer a movie, song, game, or other data, you could probably do it in a few seconds to anywhere else in your house or the world for that matter. In fact you would probably have only one box that does it all- music, games, movies, telecommunications, etc. and have terminals in every room with individualized voice controlled access. With super high speed data transfer and ultra large storage capacities who needs discs? That's a possibility I think.
