I wonder who's paying for this "free" commercial on e.g. AVzombie kind of sites ; I guess the AV flatscreen industry itself......? if we talk a lot about it, many people may almost concider it obligatory to purchase a really big screen and follow the leader to a new hype wich will give the customers a chance to spent their money again, this time on a chinese restaurant aquarium-sized screen.
In america a lot of things are bigger than in europe; I guess a big screen in a big house can appear nice, but on our often smaller walls 40" will be a good size imho; otherwise there won't be any wall left to put your [B&O] speakers in front of..............:-)
50-60" [or even bigger] black hole on / in the wall ? and watch tele in the neighbours house to make a decent watching distance possible from the screen to your chair.
It's obviously all a matter of [good] taste, so I guess we will eventually follow the "fashion", for me ; I'll keep my avant and enjoy it......
