HP ExpressCard Analog TV Tuner

[Darktech]

I'm not familiar with TV tuners since I haven't bought one before, but from the description with this I would have no need for a TV because this would make my laptop serve the same purpose. What I'm wondering about is if I can also hook up game systems to my laptop as well using this. Since I'm moving into a dorm it would be convenient if I don't have to buy a TV separately from the laptop. Also if any has bought a HP ExpressCard Analog TV Tuner before please tell me the pros and cons to it.
