I don't think many will be buying this to sit right in front of it, altough I've seen people use 55 Inch TVs as their main desk screen, those kind of people may just do that, but they're few.
On the other hand there's people like me that Like to be comfortable, I do have a 27" Monitor that I use on my desk as my Main, and yet I am looking forward to buying a 55" OLED from LG to place right on top of it, main reason why is when I'm at my bed, or at my couch or even if I just back of a meter on my chair to rest my legs on top of something and recline back, it becomes really difficult to read text in games and even to be aware of my surroundings, with my reaction time to attacks taking a big hit. So do wish for a 55" on my Room but that's for relaxing back and playing games or watching movies instead of working or reading on it And a monitor like this one might make sense for anyone who doesn't have sufficient space for 55 inch OLEDs.
Here's a rendering on how it shoud be whn I get to it (Mind you, the monitor is on a arm that is not on the rendering so I can lower it to get it out of the TV area):
