What's the difference between a monitor vs. TV other than the lack of a tuner?

Since the digital switch, I’ve been without the telly for over a year now. With Hulu, YouTube and TPB, I don’t see any reason to go back so I figure why waste the money on a tuner? Where my current TV sits I can fit a 46" so I’m looking at the Samsung 460DXN. All thoughts and opinions welcome.

a monitor might not have the red/white/yellow (or s-vid) inputs for game consoles or dvd players.
