For just computing, forget it. Quality is horrible, unless of course you have a rather large flat screen (rear projection) tv. My dad has a 60'' rear projection tv, and if I make the res as big as possible, I can kind of see whats going on.
On the tube 36'' tv in my room, it looks like ass
But I can watch music videos pretty well on it. Other then that, its all blah.
Unless, you have an LCD or Plasma Tv laying around
