If listening to music isn't a priority to you at all, at least not loud and clear, then I'd say throw down on the HTiB. I've listened to quite a few HTiB and they do fine for movies and tv. Granted, my Paradigms blow'em away, and so will any pair of good floorstanders/bookshelfs. But if you are used to listening to tv/movie audio off of your TV, my recommendation would be pick up the HTiB.
Once you start investing in quality audio equipment, you are not going to want to stop, and you wont ever want to go back. Not to mention you'll be pulling your hair out when you throw a party and drunk friends are getting uncomfortably close to expensive equipment.
Ignorance can be bliss, just remember that
