The curved screen is fantastic, but I feel like the screen needs to be 75"+ or the curve seems a gimmick. Similar to 3D, the curve has best effect when it dominates field of view. Similar to 3D, i think most people will go out their way to see that it fails too. If you do not know, the curve is to create a layered more immersive view. It works with your peripheral view to bring the scene "at you".
I love the contrast of OLEDs and I spent a lot of time watching the 55" Samsung and 55" LG. The LG looks much nicer to my eyes, and the Samsung has that typical Samsung cartoony color pallette. I am excited for OLED price to come down but I would not grab a 55" and go down in size. Newer homes seem to be built to accommodate larger TV choices and let you sit further back. Being able to place a TV on a wall creates more floor space. I do not want to lose floor space for a curved TV. The curve is cool and all but wall mounting takes priority for me. Just my 2 cents.
