Nnno, I said that you can play from your couch with all the advantages of PC gaming as a response to someone who was talking as if noone ever would want to do such a thing. I have never even suggested that playing from a couch is generally better in whatever way than playing from a chair, I'm pretty much doing what I can to not talk for other people, ever. And I, personally, just love to get off my chair that I do work all the time in and at the very least do my hobby in a different position and slightly different surroundings.
keeveek: But I'm sure your orthopedist is happy :P
Actually when you're playing a long time in a row, just remaining frozen in the same position can be fairly harmful, no matter how anatomically correct given position is.
