Wow now it looks like not owning a TV really wont matter...
And I'm of the opinion that it shouldn't. When it comes to presenting video, the best tool for the job available should be what's used.
I like the idea of the TV as a second monitor, at least in an entertainment environment. I do like watching movies and TV programs on a bigger screen set farther in front of me. It's a no brainer. It's more enjoyable. I also don't need my control interface to be as complex as a desktop computer.
I hate being a prisoner to "TV programming". I like being able to choose what I watch and when I watch it. I'd rather depend on my friends to suggest content to me than the media providers. That sounds more like a marketplace of ideas than being part of a captive audience. However, I do like the real-time aspect of TV programming to a certain degree. In a certain light, it all just becomes "release date". It's still important. "Did you see the new [...] ?" is always going to be a phrase and element in play.
I expect the trend to continue. The presentation devices and times will be abstracted from the sources/channels the programming comes from. What is a service today will be a resource tomorrow.
We don't need TV as a lifeline. We don't want TV as a lifeline. We need the communities we are a part of to serve that role.
