My Wife; Bless her(this time)had an interesting, and maybe insightfull comment to make on this subject.

She was talking to some ladies receintly about TV and home theater, and after commenting on how much better our system sounds(Wow!)with our new set-up, not one, but Two gals commented about getting HTIB, because of the small speakers and all. It seems that the bottom line, for them, and perhaps a large percentage of the listening/viewing population, is that they are not concerned with the sound, as much as they are in "just having" a home theater system. Like having a required kitchen appliance or something, kind of a status thing. It's not as though they care so much about whether the system sounds good or bad, but that they just don't care at all. (After all, having spent how many years listening to their TVs' built-in speakers...)

An added point; one of the gals was excited to comment on the fact that one of her "little speakers" is hidden in an artificial potted plant, completely out of sight!
