A minor step "forward", but I'm already well beyond it.
Why should this be shackled to your home cable subscription? Why would it matter where you are located? If you are paying $100/month to Cox, why would they care that you are in a Comcast neighborhood? In fact, shouldn't they be delighted to sell you their service?
The cable companies are monopolies because of the physical realities of laying copper cables beneath all the streets in a city. The city would contract with one company to do this, because it didn't make sense to lay down half a dozen sets of such wires and deal with the inevitable cross-interruptions when Company A goes to repair its cables and cuts through those of Company B, etc. Each cable TV company contracts with a finite number of networks/stations to deliver content on those copper wires because there are only so many signals which can be multiplexed on a single coax cable before you get interference. Each network shows just one show at a time because that's all that they can, so you have a schedule of times when shows are on and when a show is not on it's not available.
None of that is necessary. The Internet is a common carrier. You don't need a "local" company to aggregate your content for you; it can come in quite efficiently over those laid cable wires to your house or your work or your hotel room, even if three different companies laid the three sets of wires into the ground. There are no needs for network schedules; any show can be streamed to anyone at any time.
We should be pushing forward into a post-cable/post-network world. In that world the aspects of the cable and network layers that need to be retained or replaced are (1) curation, (2) cost aggregation, (3) delivery, (4) navigation. (3) is well taken care of, although the cable company sees this as a significant demotion and fights it tooth and nail. (2) hasn't happened yet in a universal way, but Netflix et al are working that angle; Apple has for the most part ignored (2) altogether. (1) is forming somewhat organically between social media, podcasts, and blogs. (4) is the domain of AppleTV, GoogleTV, the Kinect/XBox thing, etc.
This is a step off to the side. Yeah, you can now use your iPad as a TV, almost as fancy as a 1984 WatchMan! But you still are paying $100+ a month for a bunch of shows you don't care to watch, to a monopoly which doesn't need to exist anymore, and all rights to what you've paid for end (legally at least) at your front door. Push forward instead. Cut the cord, take the leap, and sip the real future
