But your assumption is that 100% of the rest must use a monitor with their PC and it must not be in the living room, and they must use a TV with their console and it must be in the living room.
Seems like I'm the one saying people have options, and you're the one saying, "No, people must conform to what I believe is normal!"
Let's just go back a bit, you said "It's weird that people have this idea that a console must be in the living room connected to a TV, and a PC must be on a desk connected to a monitor."
Its not weird, its the norm. You are an exception to the rule, I'm giving you the fact that a few people do it, but its a tiny fraction. I'm not sure how you can keep arguing it.
