Good post HTIB is OK for many
I am not one who bashes HTIB systems. Many are well served by them and I had one myself once, a Kenwood. Living in an apartment temporarily I wound up buying a Kenwood HTIB and while it wasn't great, it was a lot better than either the TV speakers or a stereo setup. Movies were more enjoyable and music was OK. Also a lot of folks don't want to hassle with the setup and configuration of an HT setup. If they start to spend over a $1000 I might counsel them to consider separates, depends who they are and what they are after.
I try not to spend other peoples money, even by inference, like slamming their choices in HT, automobiles, camera gear, etc. I will gladly give advice, and after understanding what they are trying to accomplish, I almost always start with "what are you looking to spend"? If I feel that by spending a little extra, they can get a much better (name it - camera, receiver, auto, etc) then I tell them and why I feel that way, but I let them make the choice. Most people can buy a better HT setup by not spending absurd amounts on interconnects, speaker wire, etc.
A lot of times purists and aficionados have a hard time understanding that not everyone will appreciate the gear, they just want to listen or watch or drive or whatever, the things we love and lust after are appliances to them
