ok, my two cents since you asked (sorry for limited english):
designwise, I am absolutely thrilled about my bv9 - always loved the design, always dreamed about owning one.
i have a playstation 3, apple tv and a digital receiver connected to it, and the picture of the bv9 looks great. also, with my beolabs 5 I have a great sound.
the one thing I am unhappy about is the software side, meaning the ease of use (it was a pain putting everything together). with the beo5 remote I was never happy, totally confusing, now i only use the beo4 that came with my beovision 7.
as a matter of fact, I still admire the design of the bv7 more, because the dvd is built right in, you just press a button, and boom... If I had the money, I would have gotten the BV7-55, but look at the price and compare it to recent (well received) LCD's by Samsung...
Now this year there are interesting developments, just look at the 55' OLED that LG presented. And since one has to choose other labels for Bluray and so on (ergo different screen menues and in worst case scenarios more plastic remotes on the table), B&O seems to make less sense in the future (at least to me). Should Apple this year bring something to the market that has a good enough picture quality and some smart ideas about sound like that Bose TV (sorry Bose haters...), I will be very tempted to get another TV....
However, I always wanted to own a nice B&O TV, and I am very, very happy with my BV9 for now.
