Yeah, if you have DSL cable, or dish or whatever, there is an HDMI chord that connects the cable box to the tv, you can take it out of the cable box, and plug it into your laptop. Like Bacon said, if you want, you can even get a wireless mouse and key board and navigate from your bed.
Hulu I haven't signed up for yet but would like to. It is, like Mr X said, more TV and less movies, it Hulu Plus has far more tv shows, and more current content. I think the price is about the same. Sign up for a free week and see what you think. I've heard it's way better the netflix.
