This weekend we had a chance to utilize Comcast's On Demand service, renting one movie and watching some previously aired episodes. In all, it was a good experience, bringing my entertainment immediately, without waiting for time to download, or taking up hard disk space. Also, the cost for a relatively new movie was only $3.99, contrasted with the $9.99 to $12.99 I could expect to pay for a movie from iTunes. I continue to feel that iTunes is a much better option for music than it is for video, to date.That's the background behind my most recent contribution to The Apple Blog, titled How Will Apple Compete With “On Demand”?. Per agreement with them, I will not be cross-posting the piece, but instead, have provided a link. Enjoy.
