I'm not trying to hijack this thread at all, and this question may have already been answered here, but I have lost track with all the high tech acronyms, etc, so here goes. Is there something, maybe like an aircard, that you can stick in a laptop and receive TV signals? Digital signals? That would be perfect for us ramblin' folks who don't want to mess with a sat dish...
You might consider using a laptop with a wireless broadband internet connection. It's as if your computer connect through a cell phone connection, in simplified terms. I don't think you are going to get much live programming, though. You could download video, and most shows on TV are available soon after airing.
The one sitcom I watch is The Office, and I've saw more episodes this past season on a laptop than on a TV screen. I did need to wait a day to see them.
I will say that while the wireless broadband is nice, it's simply not as good as using the wires that come into our apt.
