If you can do it from your Phone, Tablet or computer, then it will be.
Not necessarily. Between storage limitation (my DVR has a TB hardrive, no phone or tablet has that) and UI considerations (hooking a computer to a TV is kind of a pain) the set top box still has a clear market. Add to that the fact that many of the boxes can be controlled and accessed from the web (really dependent on your cable company, they all could be accessed from the web, the question is does your cable company choose to do it), and there’s simply no reason for it to go away. It’s a much more useful and dynamic device than this article wants to pretend.
