I agree with you that the B&O TVs are overpriced. Some of them offer the ability to be the core of an integrated AV and multiroom setup, which has advantages, but I've never been able to rationalize the cost differences. I've always gone with other brands, and have kept my audio for video and audio only setups separate. I use B&O for audio only, and an inexpensive Marantz AVR and an Infinity speaker setup for my video system. When I bought my latest 65 inch Panasonic plasma VT series, allegedly B&O was using the same panel for the Beovision 12. I paid $3k for the Panny, the BV12 was about $20k, and while it did have a center channel and a surround decoder, I have less than $800 in the AVR and speaker bar, which still makes the BV12 very expensive by comparison.
Different people will have different opinions of course, different needs, and priorities. For me, at least, its always been preferable to not go with a BV.
