Here is an interesting take on HD downloads from David Pogue, New York Times technology columnist. I’ve read Pogue for years, way back to his MacWorld days so I respect his opinion. The article is timely (2/21/08) and reviews several of the more popular download services Apple TV, TiVo/Amazon Unbox, Xbox 360, and Vudu. David’s prediction is wide spread adoption of downloadable High Def movies is years off.
His closing sentance reads, "Clearly, spinning silver discs will remain the dominant movie-delivery method for years to come."
