You kind of have to do that to make Hulu and similar sites actually work in the living room due to the ridiculous licensing restrictions on a lot of their content disallowing phone/Xbox/360/Wii/set top box usage.
Yes with a Mac Mini connected to a LCD TV you have a ton more choices(hulu, cbsnews.com/video, tv.com & others).
It's not the same user experience as a TV, but for me it's better. It allows me to watch/listen to shows/movies in one tab while reading articles, instant messaging friends & other things within other tabs.
